This cookbook will help you to comprehensively test your networks' major functions on a regular basis."Nagios Core Administration Cookbook" will show you how to use Nagios Core as a monitoring framework that understands the layers and subtleties of the network for intelligent monitoring and notification behaviour. Nagios Core Administration Guide introduces the reader to methods of extending Nagios Core into a network monitoring solution. The book begins by covering the basic structure of hosts, services, and contacts and then goes on to discuss advanced usage of checks and notifications, and configuring intelligent behaviour with network paths and dependencies. The cookbook emphasizes using Nagios Core as an extensible monitoring framework. By the end of the book, you will learn that Nagios Core is capable of doing much more than pinging a host or to check if websites respond.

You should have a Nagios Core 3.0 or newer server running with a few hosts and services configured already, and have a plugin that you would like to remove from the server. In this instance, we'll remove the now unneeded check_rsync plugin from our Nagios Core server.

        command_name  check_rsync
        command_line  $USER1$/check_rsync -H $HOSTADDRESS...
