Popularly known as ELK Stack has been recently re-branded as Elastic Stack. It is a powerful collection of three open source tools: Elasticsearch, Logstash, and Kibana.

It lets you search through all the logs at a single place and identify the issues spanning through multiple servers by correlating their logs within a specific time frame.
