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.

Monitoring Nagios performance with Nagiostats


In this recipe, we'll learn how to use the nagiostats utility to get some statistics about the performance of a Nagios Core process, and the states of the hosts and services that it monitors.

Optionally, we'll also show how to use the mrtg.cfg file built in the Nagios Core source distribution at ./configure time to set up graphs built by mrtg (Multi-Router Traffic Grapher), and link to the graphs in the menu of the web interface. The Nagios Core source distribution includes some files to assist with this, which we'll use here.

Getting ready

You will need a Nagios Core 3.0 or newer server installed and running to invoke nagiostats. Older versions do include the utility, but there is not quite as much information returned.

If you would like to run the mrtg graphing as well, which is highly recommended, you should have mrtg and its helper program, indexmaker, installed on your system. If you are already graphing other things with mrtg, don't worry...
