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.

We'll use this as a simple diagnostic check to make sure that the host's network stack is responding in a consistent and timely fashion, in much the same way as an administrator might use the ping command interactively to check the same properties.

Getting ready

You should have a Nagios Core 3.0 or newer server with at least one host configured already. We'll use the example of corinth.naginet, a host defined in its own file. You should also understand the basics of how hosts and services relate, which is covered in the recipes of Chapter 1, Understanding Hosts, Services, and Contacts.

How to do it...

We can add a new PING service check to our existing host as follows:

  1. Change to the objects configuration directory for Nagios Core. The default path is /usr/local/nagios/etc/objects. If you've...
