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.

Configuring notification periods

In this recipe, we'll adjust the configuration for a service that has been bugging us with notifications late at night. We'll arrange to keep checking this host, sparta.naginet, on a 24x7 basis, but we'll prevent it from sending notifications outside of work hours, using two of the predefined time periods in the default Nagios Core configuration.

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.

How to do it...

We can define the check_period and notification_period plugins for our host as follows:

  1. Change to the objects configuration directory for Nagios Core. The default is /usr/local/nagios/etc/objects. If you've put the definition for your host in a different file, then move to its directory instead.

    # cd /usr/local/nagios/etc/objects
  2. Edit the file containing your host definition, and find the definition within the file:

    # vi sparta...
