In this tutorial, we will show you how to install the Graylog Monitoring server on CentOS 8. Alternately, Graylog is also effective when working with raw strings, such as Syslog. Graylog is primarily used as a stash for logs for any web application in use. It facilitates work over the logs that the main server aggregates. Similarly, Graylog features a web interface for the visualization of data. It has a main server to receive data from the clients that may be installed over different servers.
