Managing an infrastructure of servers is a non-trivial task. When one cluster is misbehaving, logging in to multiple servers, checking each log, and using multiple filters until you find the culprit is not an efficient use of resources.
The first step to improve the methods that handle your infrastructure or applications is to implement a centralized logging system. This will enable you to gather logs from any application or system into a centralized location and filter, aggregate, compare, and analyze them. If there are servers or applications, there should be a unified logging layer.
Thankfully, we have an open source stack to simplify this. With the combination of Elasticsearch, Fluentd, and Kibana (EFK), we can create a powerful stack to collect, store, and visualize data in a centralized location.
