Elastic Stack
The Elastic Stack (or ELK Stack) is a group of open-source tools that help you analyze and visualize data in real-time. It makes it easier for you to understand your logs and data. (As an aside, the term ‘stack’ generally refers to a group of tools that build on one another.)
There are four parts to the Elastic Stack
These are:
- Elasticsearch: A way to store, search through, and analyze your data using JSON.
- Kibana: A web-based tool to visualize the data in Elasticsearch.
- Logstash: A server-side app that processes and normalizes data from multiple different sources.
- Beats: A simple lightweight way to send data from thousands of different machines to either Logstash or Elasticsearch.
