Centralized Logging with Logstash and Kibana On CentOS 7

Centralized logging can be very useful when attempting to identify problems with your servers or applications, as it allows you to search through all of your logs in a single place. It is also useful because it allows you to identify issues that span multiple servers by correlating their logs during a specific time frame. This series will teach you how to install Logstash and Kibana on Ubuntu, then how to add more filters to structure your log data. Then it will teach you how to use Kibana.
  1. How To Install Elasticsearch, Logstash, and Kibana (ELK Stack) on CentOS 7
