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.

Introduction


The Nagios Core web interface is an administrator's first port of call to see the current status of the network being monitored. By way of CGI and PHP scripts, it allows an overview of the general performance of all the hosts and services being monitored. It also provides information about their current states and how checks are performed. This allows considerably more detail than that which is normally contained in e-mailed notifications.

In most respects, the Nagios Core web interface (without any addons) is designed for the display of information rather than controlling or configuring the server, but there are some things that can be done from it to actually change the way Nagios Core is running. These include the following:

  • Disabling or enabling active and passive checks, event handlers, notifications, and flap detection, whether for all hosts and services or specific ones

  • Sending custom notifications about a host or service that don't necessarily correspond to an actual state...
