Elastic Stack

This is also referred to ELK, and is an acronym that stands for Elasticsearch, Logstash and Kibana

This is a trio of tools that <www.elasticsearch.org> has packaged up into a simple and flexible way to handle, store and visualize data. Logstash collects the logs, parses them and stores them in Elasticsearch. Kibana is a web application that knows how to to talk to Elasticsearch and visualizes the data.

Quite simple and powerful

To make use of this tio, start by deploying in this order:

• Elasticseach (first, you have have some place to put things)
• Kibana (so you can see what’s going on in elasticsearch easily)
• Logstash (to start collecting data)

More recently, you can use the Elasticsearch Beats client in place of Logstash. These are natively compiled clients that have less capability, but are easier on the infrastructure than Logstash, a Java application.
