Nagios 4 and Monitor Your Servers on CentOS 7

Introduction

In this tutorial, we will cover the installation of Nagios 4, a very popular open source monitoring system, on CentOS 7 or RHEL 7. We will cover some basic configuration, so you will be able to monitor host resources via the web interface. We will also utilize the Nagios Remote Plugin Executor (NRPE), that will be installed as an agent on remote hosts, to monitor their local resources.

Nagios is useful for keeping an inventory of your servers, and making sure your critical services are up and running. Using a monitoring system, like Nagios, is an essential tool for any production server environment.
