Overview of this book

Network monitoring requires significantly more than just pinging hosts. 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.

Finding a plugin

In this recipe, we'll follow a good procedure for finding a plugin appropriate to a specific monitoring task. We'll start by checking to see if an existing plugin is already available to do just what we need. If we can't find one, we'll check to see if we can use another more generic plugin to solve the problem. If we still find that nothing suits, we'll visit Nagios Exchange and search for an appropriate plugin there.

Getting ready

You should have a Nagios Core 3.0 or newer server running with a few hosts and services configured already, and you'll need to have a particular service on one of those hosts, which you're not sure how to monitor.

We'll use a simple problem as an example; we have a server named troy.naginet that runs an rsync process that listens on port 873. We're already monitoring the host's network connectivity via PING, but we'd like to have Nagios Core check whether the rsync server is available and listening at all times, in case it crashes while running...
