The ELK stack is an acronym of three popular open-source projects: Elasticsearch, Logstash, and Kibana. It is an open-source and one of the most popular log management platform that collects, processes, and visualizes data from multiple data sources. It is mainly used for log analysis in IT environments. It is very helpful for a system administrator to search and analyze a large volume of data to make real-time decisions-all the time.
Elasticsearch: It is a search engine used to store all of the collected data.
Kibana: It provides a web-based interface used to search and visualize your data.
Logstash: It is a data processing interface used to collect data from several sources concurrently then sends the data to your desired stash.
In this tutorial, we will explain how to install and configure the ELK stack on Ubuntu 20.04 server.
