Docker Container Monitoring<\/p>\n<\/div>\n

At the time of writing this article, it ships with built-in support for\u00a0Docker<\/a>\u00a0(default container connector) and\u00a0runC<\/strong>; connectors for other container and cluster platforms will be added in future releases.<\/p>\n

How to Install ctop in Linux Systems<\/h3>\n

Installing the latest release of\u00a0ctop<\/strong>\u00a0is as easy as running the following commands to download the binary for your Linux distribution and install it under\u00a0\/usr\/local\/bin\/ctop<\/strong>\u00a0and make it executable to run it.<\/p>\n

$ sudo wget https:\/\/github.com\/bcicen\/ctop\/releases\/download\/v0.7.1\/ctop-0.7.1-linux-amd64  -O \/usr\/local\/bin\/ctop\r\n$ sudo chmod +x \/usr\/local\/bin\/ctop\r\n<\/pre>\n
Alternatively, install\u00a0ctop<\/strong>\u00a0via Docker using following command.<\/p>\n
$ docker run --rm -ti --name=ctop -v \/var\/run\/docker.sock:\/var\/run\/docker.sock quay.io\/vektorlab\/ctop:latest\r\n<\/pre>\n
Once you have installed\u00a0ctop<\/strong>, you can run it to list all your containers whether active or not.<\/center><\/p>\n
$ ctop\r\n<\/pre>\n
\n
\"Monitor<\/a><\/p>\n
Monitor Docker Containers<\/p>\n<\/div>\n
You can use the\u00a0Up<\/strong>\u00a0and\u00a0Down<\/strong>\u00a0arrow keys to highlight a container and click\u00a0Enter<\/strong>\u00a0to select it. You will see a menu as shown in the following screenshot. Choose\u00a0\u201csingle view\u201d<\/strong>\u00a0and click on it to inspect the selected container.<\/p>\n
\n
\"Monitor<\/a><\/p>\n
Monitor Single Docker Container<\/p>\n<\/div>\n
The following screenshot shows the single view mode for a specific container.<\/p>\n
\n
\"Inspect<\/a><\/p>\n
Inspect a Single Container<\/p>\n<\/div>\n
To display active containers only, use the\u00a0-a<\/code>\u00a0flag.<\/p>\n
$ ctop -a \r\n<\/pre>\n
\n
\"Check<\/a><\/p>\n
Check Active Docker Container<\/p>\n<\/div>\n
To display CPU as\u00a0%<\/code>\u00a0of system total, use the\u00a0-scale-cpu<\/code>\u00a0option.<\/p>\n
$ ctop -scale-cpu\r\n<\/pre>\n
You can also filter containers using the\u00a0-f<\/code>\u00a0flag, for example.<\/p>\n
$ ctop -f app\r\n<\/pre>\n
Additionally, you can select initial container sort field using the\u00a0-s<\/code>\u00a0flag, and see the\u00a0ctop<\/strong>\u00a0help message as shown.<\/p>\n
 \r\n$ ctop -h\r\n<\/pre>\n
Note that connectors for other container and cluster systems are yet to be added to\u00a0ctop<\/strong>. You can find more information from the\u00a0Ctop Github repository<\/a>.<\/p>\n
