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 demonstrate this as part of the general best practice of sending notifications to contact groups, rather than to individual contacts, which allows for more flexibility in assigning individual contacts to the appropriate groups for receiving appropriate notifications.

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 sparta.naginet, a host defined in its own file, which we'll configure to send its notifications to an existing contact group called noc.

How to do it...

We can configure notifications to be sent to our contact group as follows:

    # cd /usr/local/nagios/etc/objects
  2. Ensure that an appropriate...
