How To Install Elasticsearch, Logstash, and Kibana (ELK Stack) on Ubuntu 14.04
In this tutorial, we will go over the installation of the Elasticsearch ELK Stack on Ubuntu 14.04—that is, Elasticsearch 2.2.x, Logstash 2.2.x, and Kibana 4.4.x. We will also show you how to configure it to gather and visualize the syslogs of your systems in a centralized location, using Filebeat 1.0.x. Logstash is an open source tool for collecting, parsing, and storing logs for future use. Kibana 4 is a web interface that can be used to search and view the logs that Logstash has indexed.
