How to Use This Manual

The System Monitoring Plug-in Metric Reference Manual for Non-Oracle Database Management lists all the plug-ins metrics for database management that Enterprise Manager monitors. This manual shows all the metric help available online, eliminating the need to have the Grid Control Console up and running.

This preface describes:

- Structure of the Metric Reference Manual

- Background Information on Metrics, Thresholds, and Alerts

Structure of the Metric Reference Manual

This manual contains a chapter for each Enterprise Manager non-Oracle middleware management plug-in.

Metric Information

The information for each metric comprises a description and user action if available:

- Description
Provides an explanation following the metric name. This text defines the metric and, when available, provides additional information pertinent to the metric.

- User Action (if available)
Suggestions of how to solve the problem causing the alert.

Additional Information

The following table describes the additional information that may be provided for a metric.

Column Header

Column Definition

Target Version

Version of the target, for example, 9.0.2.x and 10.1.0.x. The x at the end of a version (for example, 9.0.2.x) represents the subsequent patchsets associated with that release.

Evaluation and Collection Frequency

The rate at which the metric is collected and evaluated to determine whether it has crossed its threshold. The evaluation frequency is the same as the collection frequency.

Server Evaluation Frequency

The rate at which the metric is evaluated to determine whether it has crossed its threshold. For server-generated alerts, the evaluation frequency is determined by Oracle Database internals. For example, if the evaluation frequency is 10 minutes, then when the Average File Write Time degrades to the point an alert should trigger, it could be almost 10 minutes before Enterprise Manager receives indication of the alert. This column is present in the Metric Collection Summary table only for Oracle Database 10g metrics.

Collection Frequency

The rate at which the Management Agent collects data. The collection frequency for a metric comes from the Enterprise Manager default collection file for that target type.

Upload Frequency

The rate at which the Management Agent moves data to the Management Repository. For example, upload every nth collection. The upload frequency for a metric comes from the Enterprise Manager default collection file for that target type. This column is present in the Metric Collection Summary table only when the Upload Frequency is different from the Collection Frequency.

Comparison Operator

The comparison method Enterprise Manager uses to evaluate the metric value against the threshold values.

Default Warning Threshold

Value that indicates whether a warning alert should be initiated. If the evaluation of the warning threshold value returns a result of TRUE for the specified number of consecutive occurrences defined for the metric, an alert triggers at the warning severity level.

Default Critical Threshold

Value that indicates whether a critical alert should be initiated. If the evaluation of the critical threshold value returns a result of TRUE for the specified number of consecutive occurrences defined for the metric, an alert triggers at the critical severity level.

Consecutive Number of Occurrences Preceding Notification

Consecutive number of times a metric's value reaches either the warning threshold or critical threshold before a notification is sent.

Alert Text

Message indicating why the alert was generated. Words that display between percent signs (%) denote variables. For example, Disk Utilization for %keyValue% is %value%% could translate to Disk Utilization for d0 is 80%.

Background Information on Metrics, Thresholds, and Alerts

A metric is a unit of measurement used to determine the health of a target. It is through the use of metrics and associated thresholds that Enterprise Manager sends out alerts notifying you of problems with the target.

Thresholds are boundary values against which monitored metric values are compared. For example, for each disk device associated with the Disk Utilization (%) metric, you can define a different warning and critical threshold. Some of the thresholds are predefined by Oracle, others are not.

Once a threshold is reached, an alert is generated. An alert is an indicator signifying that a particular condition has been encountered and is triggered when one of the following conditions is true:

- A threshold is reached.

- An alert has been cleared.

- The availability of a monitored service changes. For example, the availability of an application server changes from up to down.

- A specific condition occurs. For example, an alert is triggered whenever an error message is written to a database alert log file.

Alerts are detected through a polling-based mechanism by checking for the monitored condition from a separate process at regular, predefined intervals.

See Also:

See the Oracle Enterprise Manager Concepts manual and the Enterprise Manager online help for additional information about metrics, thresholds, and alerts

Editing

Out of the box, Enterprise Manager comes with thresholds for critical metrics. Warning and critical thresholds are used to generate an alert, letting you know of impending problems so that you can address them in a timely manner.

To better suit the monitoring needs of your organization, you can edit the thresholds provided by Enterprise Manager and define new thresholds. When defining thresholds, the key is to choose acceptable values to avoid unnecessary alerts, while still being notified of issues in a timely manner.

You can establish thresholds that will provide pertinent information in a timely manner by defining metric baselines that reflect how your system runs for a normal period of time.

The metrics listed on the Edit Thresholds page are either default metrics provided by Oracle or metrics whose thresholds you can change.

Specifying Multiple Thresholds

The Specifying Multiple Thresholds functionality allows you to define various subsets of data that can have different thresholds. By specifying multiple thresholds, you can refine the data used to trigger alerts, which are one of the key benefits of using Enterprise Manager.The key in specifying multiple thresholds is to determine how the comparison relates to the metric threshold as a whole. What benefit will be realized by defining a more stringent or lax threshold for that particular device, mount point, and so on?For example, using the Average Disk I/O Service Time metric, you can define warning and critical thresholds to be applied to all disks (sd0 and sd1), or you can define different warning and critical thresholds for a specific disk (sd0). This allows you to adjust the thresholds for sd0 to be more stringent or lax for that particular disk.

Accessing Metrics Using the Grid Control Console

To access metrics in the Grid Control Console, use the All Metrics page associated with a particular target by doing the following:

1. From the Grid Control Console, choose the target.

2. On the target's home page, click All Metrics in the Related Links section.

3. On the All Metrics page, choose the metric of interest and click Help. The help for that metric displays.

Default Collection Interval — Every 15 minutes

Table 5-1 .NET CLR Exceptions Metrics

Metric

Description and User Action

Exceptions Thrown

This counter indicates the total number of exceptions generated in managed code since the application restarted.

Exceptions are very costly and can severely degrade your application performance. You should investigate your code for application logic that uses exceptions for normal processing behavior. Response.Redirect, Server.Transfer, and Response.End all cause a ThreadAbortException in ASP.NET applications. This counter value should be less than 5 percent of Request/sec for the ASP.NET application. If more than 1 request in 20 throw an exception, be attentive to these occurrences.

Exceptions Thrown Per Sec

This counter indicates the total number of exceptions generated per second in managed code.

Exceptions are very costly and can severely degrade your application performance. You should investigate your code for application logic that uses exceptions for normal processing behavior. Response.Redirect, Server.Transfer, and Response.End all cause a ThreadAbortException in ASP.NET applications. This counter value should be less than 5 percent of Request/sec for the ASP.NET application. If more than 1 request in 20 throw an exception, be attentive to these occurrences.

Exceptions Thrown Since Last Upload

Displays the total number of exceptions thrown during the last metric collection.

The metrics in the .NET CLR Interop category provide information about an application's interaction with COM components, COM+ services, and external type libraries.

Default Collection Interval — Every 15 minutes

Table 5-2 .NET CLR Interop Metrics

Metric

Description and User Action

CCWs

Displays the current number of COM callable wrappers (CCWs). A CCW is a proxy for a managed object being referenced from an unmanaged COM client. This counter indicates the number of managed objects referenced by unmanaged COM code.

This value must be as low as possible. If this number is high, determine whether you can redesign this part of the application to reduce the number of transitions needed. If you see memory expanding (or not becoming freed when it should have been) and this counter is increasing, this may suggest that unmanaged code is holding on to some of your managed objects, thereby causing memory either not being freed or increasing.

Marshalling

Displays the total number of times arguments and return values have been marshalled from managed to unmanaged code, and vice versa, since the application started.

This value must be as low as possible. If this number is high, determine whether you can redesign this part of the application to reduce the number of transitions needed.

Stubs

Displays the current number of stubs created by the common language runtime. Stubs are responsible for marshaling arguments and return values from managed to unmanaged code, and vice versa, during a COM interop call or a platform invoke call.

This value must be as low as possible. For calls being made from managed and unmanaged code and vice-versa, this counter indicates the interaction between COM and managed code. If this number is high, determine whether you can redesign this part of the application to reduce the number of needed transitions.

.NET CLR JIT Metrics

The metrics in the .NET CLR Jit category provide information about Just-in-Time (JIT) information for the code that has just been compiled. JIT compilation is used to compile IL methods to native machine language immediately before execution of the methods.

Default Collection Interval — Every 15 minutes

Table 5-3 .NET CLR JIT Metrics

Metric

Description and User Action

IL Bytes Jitted

Displays the total number of Microsoft Intermediate Language (MSIL) bytes compiled by the Just-in-Time (JIT) compiler since the application started.

A high value for this performance counter indicates performance overhead. The JIT is a runtime optimizing compiler. You can consider improving the startup time of client applications by compiling your application at install time, using the NGEN.exe utility.

Methods Jitted

Displays the total number of methods JIT-compiled since the application started. This counter does not include pre-JIT-compiled methods.

A high value for this performance counter indicates performance overhead. The JIT is a runtime optimizing compiler. You can consider improving the startup time of client applications by compiling your application at install time, using the NGEN.exe utility.

Standard Jit Failures

Displays the peak number of methods the JIT compiler has failed to compile since the application started.

A high value for this counter indicates a problem with the JIT compiler. This failure can occur if the IL cannot be verified, or if there was an internal error in the JIT compiler. Check the .NET framework setup to troubleshoot.

.NET CLR Loading Metrics

The metrics in the .NET CLR Loading category provide information assemblies, classes, and application domains that are loaded.

Default Collection Interval — Every 15 minutes

Table 5-4 .NET CLR Loading Metrics

Metric

Description and User Action

Load Failures

Displays the peak number of classes that have failed to load since the application started.

Load failures can occur for many reasons, such as inadequate security or invalid format. Check your code to fix the problem.

Application Domains Loaded Since Last Upload

Displays the number of application domains loaded in this application during the last metric collection.

Often, especially for security reasons, you cannot avoid using multiple AppDomains. However, doing so can limit performance at startup. You can reduce the impact of multiple App Domains by loading assemblies as domain neutral, enforcing efficient cross-AppDomain communication, using NeutralResourcesLanguageAttribute, and using serialization wisely.

Application Domains Unloaded Since Last Upload

Displays the number of application domains unloaded in this application during the last metric collection.

Often, especially for security reasons, you cannot avoid using multiple AppDomains. However, doing so can limit performance at startup. You can reduce the impact of multiple App Domains by loading assemblies as domain neutral, enforcing efficient cross-AppDomain communication, using NeutralResourcesLanguageAttribute, and using serialization wisely.

Bytes in Loader Heap

Indicates the current size (in bytes) of committed memory by the class loader across all AppDomain(s). Committed memory is the physical memory for which space has been reserved in the paging file on disk.

This counter must be in a steady state; otherwise, large fluctuations in this counter indicate there are too many assemblies loaded per AppDomain. Change the page file size accordingly to improve performance.

Current Application Domains

Displays the current number of application domains loaded in this application.

The value should be same as the number of Web applications plus one. The additional application is the default application domain loaded by the ASP.NET worker process. Often, especially for security reasons, you cannot avoid using multiple AppDomains. However, doing so can limit performance at startup. You can reduce the impact of multiple App Domains by loading assemblies as domain neutral, enforcing efficient cross-AppDomain communication, using NeutralResourcesLanguageAttribute, and using serialization wisely.

Current Assemblies

Displays the current number of assemblies loaded across all application domains in the currently running application. It includes the Application Domains in the system. ASP.NET Web pages (.aspx files) and user controls (.ascx files) are "batch compiled" by default, which typically results in one to three assemblies, depending on the number of dependencies. An unusually high number of loaded assemblies can cause excessive memory consumption.

Try to minimize the number of Web pages and user controls without compromising the efficiency of workflow. Assemblies cannot be unloaded from an application domain. To prevent excessive memory consumption, the application domain is unloaded when the number of recompilations (.aspx, .ascx, .asax) exceed the limit specified by <compilation numRecompilesBeforeAppRestart=/>.

Note: If the <%@ page debug=%> attribute is set to true, or if <compilation debug=/> is set to true, batch compilation is disabled.

Current Classes Loaded

Displays the current number of classes loaded in all assemblies.

If this value is too high, consider increasing the physical memory to improve performance.

Load Failures Since Last Upload

Displays the peak number of classes that have failed to load during the last metric collection.

Load failures can occur for many reasons, such as inadequate security or invalid format. Check your code to fix the problem.

Time Loading Percent

Reserved for future use.

Total Application Domains

Displays the peak number of application domains loaded since the application started.

Often, especially for security reasons, you cannot avoid using multiple AppDomains. However, doing so can limit performance at startup. You can reduce the impact of multiple AppDomains by loading assemblies as domain neutral, enforcing efficient cross-AppDomain communication, using NeutralResourcesLanguageAttribute, and using serialization wisely.

Total Application Domains Unloaded

Displays the peak number of application domains unloaded since the application started.

Often, especially for security reasons, you cannot avoid using multiple AppDomains. However, doing so can limit performance at startup. You can reduce the impact of multiple App Domains by loading assemblies as domain neutral, enforcing efficient cross-AppDomain communication, using NeutralResourcesLanguageAttribute, and using serialization wisely.

Total Assemblies

Displays the total number of assemblies loaded since the application started.

Try to minimize the number of Web pages and user controls without compromising the efficiency of workflow. Assemblies cannot be unloaded from an application domain. To prevent excessive memory consumption, the application domain is unloaded when the number of recompilations (.aspx, .ascx, .asax) exceed the limit specified by <compilation numRecompilesBeforeAppRestart=/>.

.NET CLR Locks and Threads Metrics

The metrics in the .NET CLR Locks and Threads category provide information about managed locks and threads that an application uses.

Default Collection Interval — Every 15 minutes

Table 5-5 .NET CLR Locks and Threads Metrics

Metric

Description and User Action

Contention Rate Per Sec

Displays the rate at which threads in the runtime unsuccessfully attempt to acquire a managed lock.

Sustained nonzero values should cause concern. If this number is increasing, a bottleneck exists in the code. This area in the code is synchronized, so only one thread at a time enters it, but it is being "hammered" by multiple threads that are all attempting to get into this piece of code. To resolve this bottleneck, find this piece of code and determine how you can avoid this situation.

Contentions Since Last Upload

Displays the total number of times that threads in the runtime have attempted to acquire a managed lock unsuccessfully during the last metric collection.

Sustained nonzero values should cause concern. If this number is increasing, a bottleneck exists in the code. This area in the code is synchronized, so only one thread at a time enters it, but it is being "hammered" by multiple threads that are all attempting to get into this piece of code. To resolve this bottleneck, find this piece of code and determine how you can avoid this situation.

Current Logical Threads

Displays the number of current managed thread objects in the application. This counter is not an average over time; it just displays the last observed value.

This counter maintains the count of both running and stopped threads. A value that is too high may be a cause of concern.

Current Physical Threads

Displays the number of native operating system threads created and owned by the common language runtime to act as underlying threads for managed thread objects.

A value that is too high indicates performance bottlenecks. If this value is too high, try to refactor the code to reduce the number of spawned threads to an optimal value.

Current Queue Length

Displays the total number of threads that are currently waiting to acquire a managed lock in the application.

You may want to run dedicated tests for a particular piece of code to identify the average queue length for the particular code path. This helps you identify inefficient synchronization mechanisms.

Current Recognized Threads

Displays the number of threads that are currently recognized by the runtime; they have a corresponding .NET thread object associated with them. These threads are not created by the CLR. They are created outside the CLR, but have since run inside the CLR at least once. Only unique threads are tracked. Threads with same thread ID re-entering the CLR or recreated after thread exit are not counted twice.

Queue Length Peak

Displays the total number of threads that waited to acquire a managed lock since the application started.

You may want to run dedicated tests for a particular piece of code to identify the average queue length for the particular code path. This helps you identify inefficient synchronization mechanisms.

Queue Length Per Sec

Displays the number of threads per second that are waiting to acquire a lock in the application.

You may want to run dedicated tests for a particular piece of code to identify the average queue length for the particular code path. This helps you identify inefficient synchronization mechanisms.

Total Contentions

Displays the total number of times that threads in the runtime have attempted to acquire a managed lock successfully.

Sustained nonzero values may be a cause of concern. You may want to run dedicated tests for a particular piece of code to identify the contention rate for the particular code path.

Total Recognized Threads

Displays the total number of threads that have been recognized by the runtime since the application started.

.NET CLR Memory Metrics

The metrics in the .NET CLR Memory category provide information about managed and unmanaged memory consumption.

Default Collection Interval — Every 15 minutes

Table 5-6 .NET CLR Memory Metrics

Metric

Description and User Action

Bytes in All Heaps

Displays the current memory allocated in bytes on the garbage collection heaps. This counter is the sum of four other counters — Gen 0 Heap Size, Gen 1 Heap Size, Gen 2 Heap Size, and Large Object Heap Size. The value of this counter is always less than the value of Process/Private Bytes, which also includes the native memory allocated for the process by the operating system. Private Bytes - # Bytes in all Heaps is the number of bytes allocated for unmanaged objects.

If this counter continues to rise, there is a managed leak. Some managed objects are always being referenced and are never collected.

Pinned Objects

When .NET-based applications use unmanaged code, these objects are pinned in memory. That is, they cannot move around because the pointers to them would become invalid. These can be measured by this counter, which displays the number of pinned objects encountered in the last garbage collection.

Too many pinned objects affect the performance of the garbage collector, because they restrict its ability to move objects and organize memory efficiently. You can also pin objects explicitly in managed code, such as reusable buffers used for I/O calls. Try to reduce the number of pinned objects in the code.

Generally, this number shouldn't be too high if you don't call to unmanaged code too often. If this counter is increasing, it might suggest that you are pinning objects due to passing them into unmanaged code and not releasing the unmanaged code, or you explicitly pinned objects and forgot to unpin them.

If this counter is increasing and the Virtual Bytes counter is also increasing, pin objects are being done too often and the GC cannot effectively compact the heap. This forces the heap to reserve additional virtual memory so the GC heap can expand and accommodate the requested needs of allocation.

Sink Blocks in Use

Displays the current number of synchronization blocks in use. Synchronization blocks are per-object data structures allocated for storing synchronization information. Synchronization blocks hold weak references to managed objects and must be scanned by the garbage collector. Synchronization blocks are not limited to storing synchronization information; they can also store COM interop metadata.

This counter indicates performance problems with heavy use of synchronization primitives. If this counter continues to increase, examine all the locations where you are using synchronization objects and determine if they are really needed.

Time in Garbage Collection Percent

Displays the percentage of elapsed time that was spent performing a garbage collection since the last garbage collection cycle.

This counter should average about 5 percent for most applications when the CPU is 70 percent busy, with occasional peaks. As the CPU load increases, so does the percentage of time spent performing garbage collection. Keep this in mind when you measure the CPU. The most common cause of a high value is making too many allocations, which may be the case if you are allocating on a per-request basis for ASP.NET applications. Study the allocation profile for your application if this counter shows a higher value.

.NET CLR Networking Metrics

Context Bound Objects Alloc Per Sec

Displays the number of context-bound objects allocated per second. Classes that can be bound to a context are called context-bound objects. These classes are marked with context attributes, which provide usage rules for synchronization, thread affinity, transactions, and so forth.

This counter is not an average over time; it displays the difference between the values observed in the last two samples divided by the duration of the sample interval.

Context Proxies

Displays the total number of remoting proxy objects in this process since it started. A proxy object acts as a representative of the remote objects and ensures that all calls made on the proxy are forwarded to the correct remote object.

Contexts

Displays the current number of remoting contexts in the application. A context is a boundary containing a collection of objects with the same usage rules such as synchronization, thread affinity, transactions, and so forth.

Remote Calls Per Sec

Displays the number of remote procedure calls invoked per second. A remote procedure call is a call on any object outside the caller's application domain. This counter is not an average over time; it displays the difference between the values observed in the last two samples divided by the duration of the sample interval.

More than one remote call may be required to complete a single operation. You need to divide the counter with the amount of requests to complete a single operation. This gives you the rate of operations completed per second. You might need to instrument your code to observe the request execution time.

Total Remote Calls

Displays the total number of remote procedure calls invoked since the application started.

More than one remote call may be required to complete a single operation. You need to divide the counter with the amount of requests to complete a single operation.

It allows business analysts and developers to visually model their business processes using a Visio-like design environment and then bind that visual representation to its physical implementation.The metrics in this category provide information about the Orchestration Service.

Table 7-13 Orchestrations Metrics

Metric

Description

Allocated Private Memory (MB)

Megabytes of allocated private memory for the host instance.

Allocated Virtual Memory (MB)

Megabytes reserved for virtual memory for the host instance.

Dehydratable Orchestrations

Number of orchestrations instances that can be dehydrated that are currently hosted by the host instance.

Dehydration Cycle in Progress

Indicates whether there is a dehydration cycle currently in progress.

Dehydration Cycles

Number of completed dehydration cycles.

Dehydration Threshold

Number in milliseconds that determines how aggressively orchestrations are being dehydrated. If the orchestration engine predicts that an instance is dehydratable for an amount of time longer than this threshold, it dehydrates the instance.

Idle Orchestrations

Number of idle orchestration instances currently hosted by the host instance. This refers to orchestrations that are not making progress but are not dehydratable, such as when the orchestration is blocked waiting for a receive, listen, or delay in an atomic transaction.

Message Box Database Connection Failures

Number of attempted database connections that failed since the host instance started.

Orchestrations Completed Per Sec

Average number of orchestrations completed per second.

Orchestrations Created Per Sec

Average number of orchestration instances created per second.

Orchestrations Dehydrated Per Sec

Average number of orchestration instances dehydrated per second.

Physical Memory and Application Domain Metrics

The metrics in this category provide information about loaded application domains and memory usage.

Table 7-14 Physical Memory and Application Domain Metrics

Metric

Description and User Action

Active Application Domains

Number of loaded orchestration application domains in the process. Much like the process, the application domain is designed as a security boundary that confines errors and faults to a specific domain. The application domain is designed as a virtual process that isolates applications.

Often, especially for security reasons, you cannot avoid using multiple application domains. However, doing so can limit performance at startup. You can reduce the impact of multiple application domains by loading assemblies as domain neutral, enforcing efficient cross-AppDomain communication, using NeutralResourcesLanguageAttribute, and using serialization wisely.

Average Batch Factor

Number of persistence points reached since the host instance started, divided by the number of underlying transactions.

This metric is beneficial where the Orchestration engine merges multiple atomic transactions into a single transaction. Assuming that a "persistence point" is really a segment boundary, this metric provides some substantial facts about the effect of batching atomic transactions. The greater the number, the greater the effect of "transaction batching" (that is, the less underlying transactions are being created).

Percent Used Physical Memory

Percentage of total used physical memory on the computer.

The value of this metric should be about 75%. A consistently high value of 100% may indicate a problem.

Process Metrics

The metrics in this category provide process-related information.

Table 7-15 Process Metrics

Metric

Description and User Action

Page File Bytes

Current amount of virtual memory in bytes that this process has reserved for use in the paging file(s). Paging files store pages of memory used by the process that are not contained in other files.

Paging files are shared by all processes, and the lack of space in paging files can prevent other processes from allocating memory. If there is no paging file, this metric reflects the current amount of virtual memory that the process has reserved for use in physical memory.

Page File Bytes Peak

Maximum amount of virtual memory in bytes that this process has reserved for use in the paging file(s). Paging files store pages of memory used by the process that are not contained in other files.

Percent Processor Time

Elapsed time that all process threads used the processor to execute instructions. The average value of this metric should be approximately 70%.

An instruction is the basic unit of execution in a computer, a thread is the object that executes instructions, and a process is the object created when a program is run. Code executed to handle some hardware interrupts and trap conditions are included in this count.

Private Bytes

Current size in bytes of memory that this process has allocated that cannot be shared with other processes.

Thread Count

Number of threads currently active in this process. An instruction is the basic unit of execution in a computer, and a thread is the object that executes instructions. Every running process has at least one thread.

Virtual Bytes

Current size in bytes of the virtual address space the process is using. Use of virtual address space does not necessarily imply corresponding use of either disk or main memory pages. Virtual space is finite, and the process can limit its ability to load libraries.

Working Set

Current size in bytes of the Working Set of this process. The Working Set is the set of memory pages touched recently by the threads in the process. If free memory in the computer is above a threshold, pages are left in the Working Set of a process even if they are not in use. When free memory falls below a threshold, pages are trimmed from Working Sets. If they are needed, they are soft-faulted back into the Working Set before leaving main memory.

This metric measures the number of memory pages that each process uses. If the system has sufficient memory, it can maintain enough space in the working set so that IIS 6.0 rarely must perform disk operations. One indicator of memory sufficiency is how much the size of the process working set fluctuates in response to general memory availability on the server. Significant fluctuation can indicate a lack of available memory.

Transaction Metrics

The metrics in this category provide information about database transactions.

Table 7-16 Transaction Metrics

Metric

Description

Transactional Scopes Committed Per Sec

Average number of transactions committed per second.

Transactional Scopes Compensated Per Sec

Average number of long-running or atomic scopes per second that have successfully completed compensation scopes.

8 Microsoft Commerce Server Metrics

The Microsoft Commerce Server 2002 Enterprise Edition management plug-in for Oracle Enterprise Manager provides hardware and software performance monitoring of Commerce Server using performance counters and application events. These counters can help you find hardware and software bottlenecks that may be restricting the flow of data.

This chapter provides descriptions for all Microsoft Commerce Server metric categories, and tables list and describe associated metrics for each category. The tables also provide user actions if any of the metrics for a particular category support user actions.

Active Server Pages Metrics

Table 8-1 Active Server Pages Metrics

Metric

Description and User Action

Errors Per Sec

Average number of errors that occurred per second.

Request Execution Time

Number of milliseconds required to execute the most recent request.

The value of this counter should be very close to zero. If it is not, check the code and try to determine the cause of the bottleneck that is consuming excessive execution time.

Request Wait Time

Number of milliseconds that the most recent request waited in the queue.

This value should be very close to zero (less than 100 milliseconds), because this is the amount of time a request waits in the queue before it begins processing. You do not want users to experience long wait times to process their checkout transactions. If the value of this counter is high, check the code and try to determine the cause of the bottleneck that is consuming excessive execution time.

Requests Executing

Number of requests currently executing. IIS 6.0 has many threads that can simultaneously process requests. This value should be stable. Experience will help you set a threshold for a particular site.

Requests Per Sec

Rate that Active Server Pages (ASP) are processing requests. This includes both successful and failed requests.

This counter provides and indication of the usage of the application. If this value is high, you may need to upgrade the hardware to handle the additional load.

Requests Queued

Requests waiting to be executed in the queue. There should not be a significant queue except at peak periods.

This counter should not have a high value. It should be less than the Request Queue limit.

Requests Succeeded

Number of successfully fulfilled requests. A high value indicates a healthy system.

Sessions Total

Number of sessions that have run since the service was started.

AuthFilter: Windows Authentication Cache Hits Per Sec

Number of user ID and password cache hits per second for an instance of the Windows authentication mode filter. This counter is for a specific instance on the server.

You should monitor the cache hit rate and cache miss rate counters. If the cache miss rate is high in comparison to the cache hit rate, you should increase the size of your cache using the connection string parameter.

AuthFilter: Windows Authentication Cache Misses

Total number of user ID and password cache misses for an instance of a Windows authentication mode filter. A cache hit always follows a cache miss. This counter is for a specific instance on the server, and is reset to zero after an IISRESET or server reboot.

Data Warehouse and Analysis Metrics

The metrics in this category provide information about Data Warehouse- and Analysis-related counters. Data Warehouse performance counters are used only when importing data groups, such as DTS tasks, users, and catalogs. Therefore, the Data Warehouse performance counters need to be set up as anonymous servers.

Expression Evaluator Engine Metrics

The metrics in this category provide information about the performance of EEE using the performance counters described below. The EEE consists of the evaluation core (logic), the ExpressionStore, and the ExpressionEval objects. The EEE contains an Expression Cache that caches loaded expressions, object properties, and expression results.

Table 8-9 Expression Evaluator Engine Metrics

Metric

Description and User Action

EEE: Evaluations Per Sec

Number of expressions evaluated per second.

Note: Displaying an advertisement or discount can cause more than one evaluation.

EEE: Expression Cache Size

Total number of expressions currently in the expression cache.

The EEE engine has two internal caches: the Expression Cache and the Expression Result Cache. These EEE caches increase in size dynamically as items are added to these caches. Because these caches are dynamic, they are not customizable.

To enhance the performance of the expression evaluator, it is recommended that you preload expressions into the expression cache using the LoadExpr or LoadAll methods of the ExpressionEval object.

To avoid runtime expression load operations, it is recommended that you call the loadAll method in the site Global.asa file.

EEE: Property Cache Hits

Total number of property cache hits since the server was started.

In addition to the Expression Cache, Commerce Server 2002 also includes an Expression Results Cache and an Expression Properties Cache. These caches grow or shrink dynamically as items are loaded or removed from them.

EEE: Property Reads Per Second

Total number of properties read by the Expression Evaluator since the server started.

EEE: Total Evaluation Errors

Total number of evaluation errors returned.

Marketing and Catalog Metrics

Commerce Server includes a Product Catalog System to manage products, create multilingual and multicurrency catalogs, and provide different search methods to quickly find needed products and services.

The metrics in this category provide information about the performance of the Product Catalog system using the performance counters described below.

Table 8-10 Marketing and Catalog Metrics

Metric

Description and User Action

Catalog Queries Per Sec

Number of queries made to the Product Catalog System per second. Query and FreeTextSearch record the values for the performance monitor counters. No other methods record the counters.

Commerce Server 2002 implemented the same usage profile for both base catalogs and indexed view virtual catalogs to show the activities of the Product Catalog System.

LRU Cache Flushes Per Sec

Number of items flushed out of the cache per second to accommodate new items added to the cache. Records items flushed by the LRU algorithm and items flushed manually.

The least recently used LRU cache counters indicate how well catalog caching is performing when catalog caching is used. An LRU cache that is performing well should have a low miss rate, a low flush rate, and a high hit rate.

LRU Cache Hits Per Sec

Number of cache hits per second for the cache.

The least recently used LRU cache counters indicate how well catalog caching is performing when catalog caching is used. An LRU cache that is performing well should have a low miss rate, a low flush rate, and a high hit rate. Monitor the LRU cache counters, and tune your cache to achieve a 90 percent hit rate.

LRU Cache Misses Per Sec

Number of cache misses per second for the cache.

The least recently used LRU cache counters indicate how well catalog caching is performing when catalog caching is used. An LRU cache that is performing well should have a low miss rate, a low flush rate, and a high hit rate.

LRU Cache Size

Total number of entries in the cache. Cache size can grow to 10 percent more than the size the user sets, at which time a flush occurs to return the cache size to the preset limit. LRU cache counters are grouped by site, not by the individual cache.

The least recently used LRU cache counters indicate how well catalog caching is performing when catalog caching is used. An LRU cache that is performing well should have a low miss rate, a low flush rate, and a high hit rate.

Predictor Client Average Prediction Time

Average elapsed time required for a prediction to be returned.

Predictor Total Client Model Loads

Number of models loaded since the service was last restarted.

Predictor Total Client Predictions

Total number of predictions.

Memory Metrics

The metrics in this category provide information about the performance of memory-related parameters using the performance counters described below.

Table 8-11 Memory Metrics

Metric

Description

Available Bytes

Amount of physical memory, in bytes, immediately available for allocation to a process or for system use. It is equal to the sum of memory assigned to the standby (cached), free, and zero page lists.

The value should be greater than 4 Megabytes.

Committed Bytes

Amount of committed virtual memory, in bytes. Committed memory is the physical memory that has space reserved on the disk paging file(s). There can be one or more paging files on each physical drive. This counter displays the last observed value only; it is not an average.

The value of this counter should not be more than 75 percent of physical memory.

Page Faults Per Sec

Average number of pages faulted per second. It is measured in number of pages faulted per second because only one page is faulted in each fault operation; hence, this is also equal to the number of page fault operations. This counter includes both hard faults (those that require disk access) and soft faults (where the faulted page is found elsewhere in physical memory.)

Most processors can handle large numbers of soft faults without significant consequences. However, hard faults, which require disk access, can cause significant delays.

Page Reads Per Sec

Rate at which the disk was read to resolve hard page faults. This metric shows the number of read operations without regard to the number of pages retrieved in each operation. Hard page faults occur when a process references a page in virtual memory that is not in a working set or elsewhere in physical memory, and must be retrieved from disk.

The value should be less than one page per second. If the system is actually out of memory, this is the biggest indicator of the problem. This counter is a primary indicator of the kinds of faults that cause system-wide delays. It includes read operations to satisfy faults in the file system cache (usually requested by applications) and in non-cached mapped memory files. Compare the value of Memory\\Pages Reads/sec to the value of Memory\\Pages Input/sec to determine the average number of pages read during each operation.

Network Metrics

The metrics in the Network category provide information about network performance using the performance counters described below.

Table 8-12 Network Metrics

Metric

Description and User Action

Bytes Received Per Sec

Rate, in seconds, at which bytes are received over this network adapter. The counted bytes include framing characters. This counter is a subset of Network Interface\Bytes Total/sec.

If a network card approaches its maximum capacity, another should be added. If this value approaches the capacity of the network, then a higher bandwidth network might be necessary.

Bytes Sent Per Sec

The rate, in seconds, at which bytes are sent over this network adapter. The counted bytes include framing characters. This counter is a subset of Network Interface\Bytes Total/sec.

If a network card approaches its maximum capacity, another should be added. If this value approaches the capacity of the network, a higher bandwidth network might be necessary.

Bytes Total Per Sec

Rate at which bytes are sent and received over each network adapter, including framing characters. Network Interface\\Bytes Received/sec is a sum of Network Interface\\Bytes Received/sec and Network Interface\\Bytes Sent/sec.

If a network card approaches its maximum capacity, another should be added. If this value approaches the capacity of the network, a higher bandwidth network might be necessary.

Current Bandwidth

Estimate of the current bandwidth of the network interface in bits per second (BPS). For interfaces that do not vary in bandwidth or for those where no accurate estimation can be made, this value is the nominal bandwidth.

Output Queue Length

Length of the output packet queue (in packets).

Delays exist if this value is longer than two. Try to find and eliminate the bottleneck, if possible. Since the requests are queued by the Network Driver Interface Specification (NDIS) in this implementation, this will always be 0.

Packets Outbound Discarded

Number of outbound packets chosen to be discarded even though no errors had been detected to prevent transmission.

One possible reason for discarding packets could be to free up buffer space.

Packets Outbound Errors

Number of outbound packets that could not be transmitted because of errors.

Packets Received Discarded

Number of outbound packets chosen to be discarded even though no errors had been detected that prevented transmission.

One possible reason for discarding packets could be to free up buffer space.

Packets Received Errors

Number of inbound packets containing errors that prevented them from being delivered to a higher-layer protocol.

Physical Disk Metrics

The metrics in the Physical Disk category provide information about disk performance using the performance counters described below.

Table 8-13 Physical Disk Metrics

Metric

Description and User Action

Average Disk Queue Length

Average of disk queue length. If the disk is not fast enough to keep up with read and write requests, requests will queue up.

The acceptable queue length is a function of the number of spindles in the array. Other counters that can be used to observe disk traffic include Physical Disk: Disk Reads/second and Physical Disk: Disk Writes/second.

If necessary, consider adding more physical drives, such as a Redundant Array of Inexpensive Disks (RAID) system, to increase the number of spindles that can read and write, as well as to increase data transfer rates.

Disk Reads Per Sec

Number of disk reads per second on the physical disk.

This counter should be well under the maximum capacity for the disk device. To enable this counter, run diskperf –y from the command shell and reboot the computer.

Disk Writes Per Sec

Number of disk writes per second on the physical disk.

This counter should be well under the maximum capacity for the disk device. To enable this counter, run diskperf –y from the command shell and reboot the computer.

Percent Disk Time

Percentage of elapsed time that the selected disk drive is busy servicing read or write requests.

Pipelines Metrics

A pipeline is an extensible software framework that defines and links together one or more stages of a business process, running them in sequence to complete a specific task. The metrics in this category provide information about Pipeline performance using the performance counters described below.

Table 8-14 Pipelines Metrics

Metric

Description and User Action

Average Execution Time

Average execution time in microseconds for t he particular component of the pipeline.

The execution time depends on the Service Level agreement with the client. It should not be high.

Errors Per Sec

Number of errors generated by the particular pipeline component per second.

Errors Total

The total number of Error Level 3 failures returned by the particular pipeline component (PIPEERRORLEV_FAIL) or FAILED HRESULT.

Warnings Per Sec

Number of warnings returned by the pipeline component per second.

Warnings Total

The total number of Error Level 2 warnings returned by the particular pipeline component (PIPEERRORLEV_WARN).

Process Metrics

Table 8-15 Process Metrics

Metric

Description and User Action

Creating Process ID

Process ID of the process that created the process. The creating process may have terminated, so this value may no longer identify a running process.

Handle Count

Total number of handles currently open by this process. This number is equal to the sum of the handles currently open by each thread in the process.

IO Data Bytes Per Sec

Rate at which the process is reading and writing bytes in I/O operations. This counter counts all I/O activity generated by the process to include file, network, and device I/Os.

IO Data Operations Per Sec

Rate at which the process is issuing read and write I/O operations. This counter counts all I/O activity generated by the process to include file, network, and device I/Os.

Percent Processor Time

Percentage of elapsed time that all process threads spend using the processors. An instruction is the basic unit of execution in a computer, a thread is the object that executes instructions, and a process is the object created when a program is run. Code executed to handle some hardware interrupts and trap conditions are included in this count.

The average value of this counter should be approximately 70%.

Private Bytes

Current size, in bytes, of memory that this process has allocated that cannot be shared with other processes.

Memory leaks are identified by a consistent and prolonged increase in Private Bytes. This is the best performance counter for detecting memory leaks. Values greater than 60% of total physical RAM begin to impact performance, especially during application and process restarts. An optimum value for this counter is a value whichever is minimum out of 60% of physical RAM and 800 MB.

Thread Count

Number of threads currently active in this process. An instruction is t he basic unit of execution in a processor, and a thread is the object that executes instructions. Every running process has at least one thread.

Thread count often increases when the load is too high. Its optimum value is expressed in the formula:

75 + ((maxWorkerThread + maxIoThreads) * #CPUs)

Virtual Bytes

Current size, in bytes, of the virtual address space the process is using. Use of virtual address space does not necessarily imply corresponding use of either disk or main memory pages. Virtual space is finite, and the process can limit its ability to load libraries.

The value of this counter should be 600 MB less than the size of the virtual address space; either 1.4 or 2.4 GB.

Virtual Bytes Peak

Maximum size, in bytes, of virtual address space the process has used at any one time. Use of virtual address space does not necessarily imply corresponding use of either disk or main memory pages. However, virtual space is finite, and the process might limit its ability to load libraries.

The value of this counter should be 600 MB less than the size of the virtual address space; either 1.4 or 2.4 GB.

Working Set

Current size, in bytes, of the Working Set of this process. The Working Set is the set of memory pages touched recently by the threads in the process. If free memory in the computer is above a threshold, pages are left in the Working Set of a process even if they are not in use. When free memory falls below a threshold, pages are trimmed from Working Sets. If they are needed, they are then soft-faulted back into the Working Set before leaving main memory.

This counter measures the number of memory pages that each process uses. If the system has sufficient memory, it can maintain enough space in the working set so that IIS 6.0 rarely must perform disk operations. One indicator of memory sufficiency is how much the size of the process working set fluctuates in response to general memory availability on the server. Significant fluctuation can indicate a lack of available memory.

Processor Metrics

The metric in this category provides information about processor performance.

Table 8-16 Processor Metrics

Metric

Description and User Action

Percent Processor Time

Percentage of elapsed time that all process threads used the processor to execute instructions. An instruction is the basic unit of execution in a computer, a thread is the object that executes instructions, and a process is the object created when a program is run. Code executed to handle some hardware interrupts and trap conditions are included in this count.

The value of this counter provides an indication about the processor time utilized by the applications running on the server. A consistently very high value for this counter indicates possible problems in the code and may require some refactoring of the application.

SQL Server Metrics

The metric in this category provides information about SQL server performance.

System Metrics

The metrics in the System category provide information about system performance using the performance counters described below.

Table 8-19 System Metrics

Metric

Description and User Action

Context Switches Per Sec

Combined rate at which all processors on the computer are switched from one thread to another. Context switches occur when a running thread voluntarily relinquishes the processor, is preempted by a higher priority ready thread, or switches between user-mode and privileged (kernel) mode to use an executive or subsystem service. It is the sum of Thread\\Context Switches/sec for all threads running on all processors in the computer and is measured in numbers of switches. There are context switch counters on the System and Thread objects. This counter displays the difference between the values observed in the last two samples, divided by the duration of the sample interval.

This counter shows the activities of the Product Catalog System. Heavy catalog queries can overload both the front-end Web server and the back-end catalog server. You can use the Commerce Server 2002 least recently used (LRU) cache to improve the performance of an overloaded Commerce Server 2002 Product Catalog System.

Processor Queue Length

Number of threads in the processor queue. Unlike the disk counters, this counter shows ready threads only, not threads that are running.

A sustained processor queue of less than 10 threads per processor is normally acceptable, depending on the workload. There is a single queue for processor time even on computers with multiple processors. Therefore, if a computer has multiple processors, you need to divide this value by the number of processors servicing the workload.

User Profile Management Metrics

The User Profile Management (UPM) system provides an easy-to-use User Management and Personalization API that you can use to build Commerce Server applications. The metrics in this category provide information about UPM performance using the performance counters described below.

Memory Metrics

The metrics in the Memory category represent calculated metrics that described the behavior of physical and virtual memory on the computer.

Default Collection Interval — Every 15 minutes

Table 10-14 Memory Metrics

Metric

Description and User Action

Available Mega Bytes

Total physical memory available to the operating system. This amount of available memory is compared with the memory required to run all of the processes and applications on your server. Try to keep at least 10 percent of memory available for peak use. Keep in mind that by default, IIS 5.0 uses up to 50 percent of available memory for its file cache, leaving the remaining memory available for other applications running on the server.

Cache Bytes

Current size in bytes of the file system cache. By default, the cache uses up to 50 percent of available physical memory. The counter value is the sum of Memory\System Cache Resident Bytes, Memory\System Driver Resident Bytes, Memory\System Code Resident Bytes, and Memory\Pool Paged Resident Bytes.

Committed Bytes

Amount of committed virtual memory in bytes. Committed memory is the physical memory which has space reserved on the disk paging file(s). There can be one or more paging files on each physical drive. This counter displays the last observed value only; it is not an average.

Page Faults Per Sec

Memory bottleneck due to page faults. If a process requests a page in memory and the system cannot find it at the requested location, this constitutes a page fault. If the page is elsewhere in memory, it is called a soft page fault. If the page must be retrieved from disk, it is called a hard page fault.

Most processors can handle large numbers of soft page faults without consequences, but hard page faults can cause significant delays. If the number of hard page faults is high, you might have dedicated too much memory to the caches, not leaving enough memory for the rest of the system.

Sustained hard page fault rates of over five per second are a key indicator of insufficient RAM. Try increasing the amount of RAM on your server or lowering cache sizes. Other counters that can indicate a memory bottleneck are Memory:Pages Input/sec, Memory:Page Reads/sec, and Memory:Pages per second.

Page Reads Per Sec

Number of times the disk was read to resolve hard page faults.

Pages Input Per Sec

Total number of pages read from disk to resolve hard page faults.

Pages Output Per Sec

Rate at which pages are written to disk to free up space in physical memory. Pages are written back to disk only if they are changed in physical memory, so they are likely to hold data, not code. A high rate of pages output might indicate a memory shortage. Windows writes more pages back to disk to free up space when physical memory is in short supply. This counter shows the number of pages, and can be compared to other counts of pages without conversion.

Pages Per Sec

Number of pages retrieved per second. The number should be less than one per second.

Pool Nonpaged Bytes

Monitor the pool space for all processes on the server.

Pool Paged Bytes

Shows the size, in bytes, of the paged pool. Pool Paged Bytes is calculated differently than Process\Pool Paged Bytes, so it might not equal Process(_Total )\Pool Paged Bytes.

Pool Paged Resident Bytes

Current size in bytes of the paged pool. The paged pool is an area of system memory (physical memory used by the operating system) reserved for objects that can be written to disk when they are not in use. The space used by the paged and nonpaged pools is taken from physical memory; thus, a pool that is too large denies memory space to processes.

System Cache Resident Bytes

Current size in bytes of the pageable operating system code in the file system cache. This value includes only current physical pages and excludes any virtual memory pages not currently resident.

System Code Resident Bytes

Current size in bytes of the operating system code currently in physical memory than can be written to disk when not in use. This value is a component of Memory\System Code Total Bytes.

System Driver Resident Bytes

The current size in bytes of the pageable physical memory in use by device drivers. This represents the working set (physical memory area) of the drivers. This value is a component of Memory\System Driver Total Bytes.

Transition Faults Per Sec

Rate at which page faults are resolved by recovering pages without incurring additional disk activity. Transition faults, which measure soft page faults, are counted in numbers of faults because only one page is faulted in each operation; the number of transition faults is equal to the number of pages faulted.

NBT Connection Metrics

The metrics in this category provide information about the network connectivity. If NBT connection: Bytes total/sec is close to the bandwidth of your network adapter and the other two performance counters are moderate, the network connection may be a bottleneck.

Metric

Description and User Action

Handle Count

Total number of handles currently open by this process. This number is equal to the sum of the handles currently open by each thread in this process.

The default warning and critical threshold values for this metric are set to an 'UnDefined' value. You can provide a value for the warning and critical thresholds based on your current environment and your requirements.

Page File Bytes

Current amount of virtual memory in bytes that a process has reserved for use in the paging file(s). Paging files store pages of memory used by the process. Paging files are shared by all processes, and the lack of space in paging files can prevent other processes from allocating memory. If there is no paging file, this metric reflects the current amount of virtual memory that the process has reserved for use in physical memory.

Page File Bytes Peak

Maximum amount of virtual memory in bytes that a process has reserved for use in the paging file(s). Paging files store pages of memory used by the process. Paging files are shared by all processes, and the lack of space in paging files can prevent other processes from allocating memory. If there is no paging file, this counter reflects the maximum amount of virtual memory that the process has reserved for use in physical memory.

Percent Processor Time

Percentage of time that the processor was executing a non-idle thread. It is calculated by measuring the duration that the idle thread is active during the sample interval, and subtracting that time from 100%. (Each processor has an idle thread that consumes cycles when no other threads are ready to run.) This counter is the primary indicator of processor activity, and displays the average percentage of busy time observed during the sample interval. Code executed to handle some hardware interrupts and trap conditions are included in this count.

The default warning and critical threshold values for this metric are set to an 'UnDefined' value. You can provide a value for the warning and critical thresholds based on your current environment and your requirements.

The default warning and critical threshold values for this metric are set to an 'UnDefined' value. You can provide a value for the warning and critical thresholds based on your current environment and your requirements.

Thread Count

Number of threads that were active in this process. A thread is the object that executes instructions, which are the basic units of execution in a processor. Every running process has at least one thread.

The default warning and critical threshold values for this metric are set to an 'UnDefined' value. You can provide a value for the warning and critical thresholds based on your current environment and your requirements.

Virtual Bytes

Size in bytes of the virtual address space that the process is using. Use of virtual address space does not necessarily imply corresponding use of either disk or main memory pages. Virtual space is finite, and by using too much space, the process can limit its ability to load libraries.

The default warning and critical threshold values for this metric are set to an 'UnDefined' value. You can provide a value for the warning and critical thresholds based on your current environment and your requirements.

Working Set

Current size of the memory area that the process is utilizing for code, threads, and data. The size of the working set grows and shrinks as the VMM permits. When memory is becoming scarce, the working sets of the applications are trimmed. When memory is plentiful, the working sets are allowed to grow. Larger working sets mean more code and data in memory, which increases the overall performance of the applications. However, a large working set that does not shrink appropriately is usually an indication of a memory leak.

Processor Metrics

The metrics in this category measure aspects of processor activity. The processor is the part of the computer that performs arithmetic and logical computations, initiates operations on peripherals, and runs the threads of processes.

The default warning and critical threshold values for this metric are set to an UnDefined value. You can provide a value for the warning and critical thresholds based on your current environment and requirements.

ID Process

Unique identifier of this process. ID process numbers are reused, so they only identify a process for the lifetime of that process.

IO Data Bytes Per Sec

Rate at which the process is reading and writing bytes in I/O operations. This counter counts all I/O activity generated by the process to include file, network, and device I/Os.

IO Data Operations Per Sec

Rate at which the process is issuing read and write I/O operations. This counter counts all I/O activity generated by the process to include file, network, and device I/Os.

IO Other Bytes Per Sec

Rate at which the process is issuing write I/O operations. This counter counts all I/O activity generated by the process to include file, network, and device I/Os.

Page Faults Per Sec

Rate at which page faults are occurring from the threads executing in this process. A page fault occurs when a thread refers to a virtual memory page that is not in its working set in main memory. This may not cause the page to be fetched from disk if it is on the standby list and therefore already in main memory, or if it is in use by another process with which the page is shared.

Page File Bytes

Current amount of virtual memory, in bytes, that this process has reserved for use in the paging file(s). Paging files store pages of memory used by the process that are not contained in other files. All processes share paging files, and the lack of space in paging files can prevent other processes from allocating memory. If there is no paging file, this counter reflects the current amount of virtual memory that the process has reserved for use in physical memory.

Page File Bytes Peak

Maximum amount of virtual memory, in bytes, that this process has reserved for use in the paging file(s). Paging files store pages of memory used by the process that are not contained in other files. Paging files are shared by all processes, and the lack of space in paging files can prevent other processes from allocating memory. If there is no paging file, this counter reflects the maximum amount of virtual memory that the process has reserved for use in physical memory.

Percent Privileged Time

Percentage of elapsed time that the process threads spent executing code in privileged mode. When a Windows system service is called, the service often runs in privileged mode to gain access to system-private data. This data is protected from access by threads executing in user mode. Calls to the system can be explicit or implicit, such as page faults or interrupts.

Unlike some early operating systems, Windows uses process boundaries for subsystem protection in addition to the traditional protection of user and privileged modes. Some work done by Windows on behalf of the application might appear in other subsystem processes in addition to the privileged time in the process.

Percent Processor Time

Percentage of elapsed time that all of process threads used the processor to execute instructions. An instruction is the basic unit of execution in a computer, a thread is the object that executes instructions, and a process is the object created when a program is run. Code executed to handle some hardware interrupts and trap conditions are included in this count.

The default warning and critical threshold values for this metric are set to an UnDefined value. You can provide a value for the warning and critical thresholds based on your current environment and requirements.

Percent User Time

Percentage of elapsed time that the process threads spent executing code in user mode. Applications, environment subsystems, and integral subsystems execute in user mode. Code executing in user mode cannot damage the integrity of the Windows executive, kernel, and device drivers.

Unlike some early operating systems, Windows uses process boundaries for subsystem protection in addition to the traditional protection of user and privileged modes. Some work done by Windows on behalf of the application might appear in other subsystem processes in addition to the privileged time in the process.

Private Bytes

Current size, in bytes, of memory that this process has allocated that cannot be shared with other processes.

The default warning and critical threshold values for this metric are set to an UnDefined value. You can provide a value for the warning and critical thresholds based on your current environment and requirements.

Thread Count

Number of threads currently active in this process. An instruction is the basic unit of execution in a processor, and a thread is the object that executes instructions. Every running process has at least one thread.

Virtual Bytes

Current size, in bytes, of the virtual address space the process is using. Use of virtual address space does not necessarily imply corresponding use of either disk or main memory pages. Virtual space is finite, and the process can limit its ability to load libraries.

The default warning and critical threshold values for this metric are set to an UnDefined value. You can provide a value for the warning and critical thresholds based on your current environment and requirements.

Virtual Bytes Peak

Maximum size, in bytes, of virtual address space the process has used at any one time. Use of virtual address space does not necessarily imply corresponding use of either disk or main memory pages. However, virtual space is finite, and the process might limit its ability to load libraries.

Working Set

Current size, in bytes, of the Working Set of this process. The Working Set is the set of memory pages touched recently by the threads in the process. If free memory in the computer is above a threshold, pages are left in the Working Set of a process even if they are not in use. When free memory falls below a threshold, pages are trimmed from Working Sets. If they are needed, they will then be soft-faulted back into the Working Set before leaving main memory.

Working Set Peak

Maximum size, in bytes, of the Working Set of this process at any point in time. The Working Set is the set of memory pages touched recently by the threads in the process. If free memory in the computer is above a threshold, pages are left in the Working Set of a process even if they are not in use. When free memory falls below a threshold, pages are trimmed from Working Sets. If they are needed, they will then be soft-faulted back into the Working Set before they leave main memory.

Web Proxy Service Metrics

The Web Proxy Service enables any Worldwide Web client to access internet resources using the HTTP, HTTPS, Gopher, and FTP protocols on behalf of the client.

Table 11-9 Web Proxy Service Metrics

Metric

Description and User Action

Array Bytes Received Per Sec

Tracks the rate at which data bytes are received from other ISA Server computers within the same array.

Array Bytes Sent Per Sec

Tracks the rate at which data bytes are sent from other ISA Server computers within the same array.

Average Current Array Fetches Time Per Request (Millisec)

Represents the sum of Array Bytes Sent/Sec and Array Bytes Received/Sec. This is the total rate for all data bytes transferred between the ISA Server computer and other members of the same array.

Cache Hit Percent Ratio

Determines how many Web Proxy client requests have been served using cached data (Total Cache Fetches) as a percentage of the total number of successful Web Proxy client requests to the ISA Server computer (Total Successful Requests). Its value provides a good indication of cache effectiveness. A high metric indicates that a high level of requests are being serviced from the cache, meaning faster response times. A zero metric indicates that caching is not enabled. A low metric may indicate a configuration problem. The cache size may be too small, or requests may not be cacheable.

The default warning and critical threshold values for this metric are set to an UnDefined value. You can provide a value for the warning and critical thresholds based on your current environment and requirements.

Cache Running Hit Ratio

Measures the amount of requests served from the cache as a percentage of total successful requests serviced. This ratio is the same as that measured by Cache Hit Ratio(%). The difference between these two metrics is that Cache Running Hit Ratio measures this ratio for the last 10,000 requests serviced, and Cache Hit Ratio measures this ratio since the last time that the Web Proxy service started. This means that Cache Running Hit Ratio provides a more dynamic evaluation of cache effectiveness.

Client Bytes Received Per Sec

Rate at which data bytes are received from Web Proxy clients. The value changes according to the volume of Web Proxy client requests, but a consistently slow rate may indicate a delay in servicing requests.

Client Bytes Sent Per Sec

Rate at which data bytes are sent to Web Proxy clients. The value changes according to the volume of Web Proxy client requests, but a consistently slow rate may indicate a delay in servicing requests.

Current Array Fetches Average Time Per Request (Millisec)

Provides the mean number of milliseconds required to service a Web Proxy client request that is fetched through another array member. This does not include requests for services by the Secure Sockets Layer (SSL) tunnel.

Current Average Time Per Request (Millisec)

Represents the mean number of milliseconds required to service a Web Proxy client request, not including requests serviced by the SSL tunnel. This counter can be monitored at peak and off-peak times for a comprehensive picture of how fast client requests are being serviced. A counter that is too high might indicate that the ISA Server is having difficulty handling all requests and that requests are being delayed.

Current Cache Fetches Average Time Per Request (Millisec)

Mean number of milliseconds required to service a Web Proxy client request from cache. This does not include requests for services by the Secure Sockets Layer (SSL) tunnel.

The default warning and critical threshold values for this metric are set to an UnDefined value. You can provide a value for the warning and critical thresholds based on your current environment and requirements.

Current Direct Fetches Average Time Per Request (Millisec)

Mean number of milliseconds required to service a Web Proxy client request directly to the Web server or upstream proxy. This does not include requests for services by the Secure Sockets Layer (SSL) tunnel.

The default warning and critical threshold values for this metric are set to an UnDefined value. You can provide a value for the warning and critical thresholds based on your current environment and requirements.

DNS Cache Entries

Details the current number of DNS domain name entries cached by the Web Proxy service. A high metric suggests a beneficial impact on performance, since a DNS cache entry eliminates the need for a DNS lookup, saving system resources.

DNS Cache Flushes

Details the total number of times that the DNS domain name cache has been flushed or cleared by the Web Proxy service. When there is no room left for more data in the DNS cache, the DNS cache is flushed to allow new entries to be made.

DNS Cache Hits

Tracks the total number of times the Web Proxy service found a DNS domain name within the DNS cache. This metric can be compared with previous DNS counters to find out if DNS caching is working efficiently. A low number of DNS cache hits impact performance, as every DNS lookup slows performance, particularly if a problem arises in the lookup process.

DNS Cache Hits Percent

Determines how many DNS entries have been resolved using cached data (DNS cache hits) as a percentage of the total number of DNS domain names retrieved by the Web Proxy service (DNS retrievals). A high metric means better performance because the DNS data is served from the cache, rather than incurring the overhead of resolving DNS lookups.

The default warning and critical threshold values for this metric are set to an UnDefined value. You can provide a value for the warning and critical thresholds based on your current environment and requirements.

DNS Retrievals

Represents the total number of DNS domain names that the Web Proxy service has retrieved.

Failing Requests Per Sec

Monitors the rate per second that Web Proxy client requests have completed with some type of error. This counter can be compared with Requests/Sec to indicate how well the ISA Server is servicing incoming Web requests. A high failure rate, in comparison to the rate of incoming requests, suggests that the ISA Server is having difficulty coping with all incoming requests. Connection settings for incoming Web requests may be incorrectly configured, or connection bandwidth may be insufficient.

FTP Requests

Tracks the number of File Transfer Protocol (FTP) requests made to the Web Proxy service. A consistently low counter may influence the caching policy for FTP objects.

Gopher Requests

Tracks the number of Gopher requests that have been made to the Web Proxy service.

HTTP Requests

Tracks the number of Hypertext Transfer Protocol (HTTP) requests that have been made to the Web Proxy service.

HTTPS Sessions

Represents the total number of Secure Hypertext Transfer Protocol (HTTPS) secured sessions serviced by the SSL tunnel.

Maximum Users

Tracks the maximum number of users that have connected to the Web Proxy service simultaneously. This counter can be useful for determining load usage and license requirements.

Requests Per Sec

Monitors the rate or incoming requests made to the Web Proxy service. A higher value means that more ISA Server resources will be required to service incoming requests.

Reverse Bytes Received Per Sec

Monitors the rate at which data bytes are received by the Web Proxy service from Web publishing servers in response to incoming requests. This rate can be monitored at peak and off-peak times as an indication of how the ISA Server is performing in servicing incoming Web requests.

Reverse Bytes Sent Per Sec

Monitors the rate at which data bytes are sent by the Web Proxy service to Web publishing servers in response to incoming requests. This rate can be monitored at peak and off-peak times as an indication of how the ISA Server is performing in servicing incoming Web requests.

Site Access Denied

Tracks the total number of Internet sites to which the Web Proxy service has denied access. An excessively high number might indicate an access policy that is too restrictive.

The default warning and critical threshold values for this metric are set to an UnDefined value. You can provide a value for the warning and critical thresholds based on your current environment and requirements.

Site Access Granted

Tracks the total number of Internet sites to which the Web Proxy service has granted access. This can be compared with Site Access Denied to provide a numeric summary of the results of access policy configuration.

SNEWS Sessions

Represents the total number of SNEWS sessions serviced by the SSL tunnel.

SSL Client Bytes Received Per Sec

Measures the rate at which SSL data bytes are received by the Web Proxy service from secured Web Proxy clients. This is similar to Client Bytes Received/Sec, but counts only SSL requests.

SSL Client Bytes Sent Per Sec

Measures the rate at which SSL data bytes are sent by the Web Proxy service to secured Web Proxy clients. This is similar to Client Bytes Sent/Sec, but counts only SSL requests.

SSL Client Bytes Total Per Sec

Represents the sum of SSL Client Bytes Sent/Sec and SSL Client Bytes Received/Sec. This is the total rate for all bytes transferred between the Web Proxy service and SSL clients.

Thread Pool Active Sessions

Represents the number of sessions that thread pool threads are actively servicing.

Thread Pool Failures

Represents the number of requests rejected because the thread pool was full.

The default warning and critical threshold values for this metric are set to an UnDefined value. You can provide a value for the warning and critical thresholds based on your current environment and requirements.

Thread Pool Size

Represents the number of threads in the thread pool. This thread pool represents the resources available to service client requests.

Total Array Fetches

Totals the number of Web Proxy client requests served by requesting the data from another ISA Server within this array. These requests are the result of the Cache Array Routing Protocol (CARP) algorithm, which randomly stores objects in any of the member servers cache. This metric is influenced by the cache size for each ISA Server in the array, since a server with a larger cache holds more cache items. The load factor for each server can also be configured to determine how workload is divided among array members.

Total Cache Fetches

Monitors the total number of Web Proxy client requests served by using cached data. A high number indicates a cache being fully exploited.

Total Failed Requests

Represents the total number of requests that the Web Proxy service has failed to process due to errors. Errors can result from the Web Proxy service failing to locate a requested server URL on the Internet, or because the client did not have authorized access to the requested URL. This metric should be far lower than Total Successful Requests. If it is not, this indicates that the ISA Server is failing to service requests effectively. This could be a configuration problem, indicate a connection that is too slow, or indicate an access policy that is too restrictive.

The default warning and critical threshold values for this metric are set to an UnDefined value. You can provide a value for the warning and critical thresholds based on your current environment and requirements.

Total Pending Connects

Total number of pending connections to the Web Proxy service.

The default warning and critical threshold values for this metric are set to an UnDefined value. You can provide a value for the warning and critical thresholds based on your current environment and requirements.

Total Requests

Represents the total number of requests made to the Web Proxy service. It is the total of two other counters: Total Successful Requests and Total Failed Requests.

Total Reverse Fetches

Represents the total number of incoming requests that have been served by requesting the data from Web publishing servers.

Total SSL Sessions

Represents the total number of SSL sessions serviced by the SSL tunnel.

Total Successful Requests

Represents the total number of requests that the Web Proxy service has successfully processed. This metric can be compared with Total Requests and Total Failed Requests to indicate the effectiveness of the ISA Server in servicing requests.

Total Upstream Fetches

Tracks the total number of requests that have been served by using data from the Internet or from a chained proxy computer. This metric can be compared to Total Cache Fetches to see what proportion of requests are being serviced from remote servers on the Internet or upstream proxies compared with those being serviced from the cache.

Total Users

Represents the total number of users that have ever connected to the Web Proxy service. It represents a history of past server usage.

The default warning and critical threshold values for this metric are set to an UnDefined value. You can provide a value for the warning and critical thresholds based on your current environment and requirements.

Unknown SSL Sessions

Represents the total number of unknown SSL sessions serviced by the SSL tunnel.

Upstream Bytes Received Per Sec

Indicates the rate at which the Web Proxy service receives data bytes from remote servers on the Internet or from a chained proxy computer in response to requests from the Web Proxy service. The value of this counter partially depends on the connection bandwidth. If the metric value is consistently low, this may indicate a bottleneck caused by a slow connection. Changing the bandwidth priority configuration may help in this situation, or a faster connection may be required.

Upstream Bytes Sent Per Sec

Indicates the rate at which the Web Proxy service sends data bytes to remote servers on the Internet or to a chained proxy computer. The value of this counter partially depends on the connection bandwidth. If the metric value is consistently low, this may indicate a bottleneck caused by a slow connection. Changing the bandwidth priority configuration may help in this situation, or a faster connection may be required.

Upstream Bytes Total Per Sec

Sum of Upstream Bytes Sent/Sec and Upstream Bytes Received/Sec. It represents the total rate for all bytes transferred between the Web Proxy service and remote servers on the Internet or a chained proxy server.
