If you are a person who is, or has been in the past, in charge of inspecting and analyzing system logs in Linux, you know what a nightmare that task can become if multiple services are being monitored simultaneously.<\/p>\n
In days past, that task had to be done mostly manually, with each log type being handled separately. Fortunately, the combination of\u00a0Elasticsearch<\/strong>,\u00a0Logstash<\/strong>, and\u00a0Kibana<\/strong>\u00a0on the server side, along with\u00a0Filebeat<\/strong>\u00a0on the client side, makes that once difficult task look like a walk in the park today.<\/p>\n The first three components form what is called an\u00a0ELK<\/strong>\u00a0stack, whose main purpose is to collect logs from multiple servers at the same time (also known as centralized logging).<\/p>\n
