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 the output of an SNMP query

In this recipe, we'll learn how to use the check_snmp plugin to monitor the output given by Simple Network Management Protocol (SNMP) requests.

Despite its name, SNMP is not really a very simple protocol, but it's a very common method for accessing information on many kinds of networked devices, including monitoring boards, usage meters, and storage appliances, as well as workstations, servers, and routing equipment.

Because SNMP is so widely supported and typically able to produce such a large volume of information to trusted hosts, it's an excellent way to gather information from hosts that's not otherwise retrievable from network services. For example, while checking for a PING response from a large router is simple enough, there may not be an easy way to check properties, such as the state of each of its interfaces, or the presence of a certain route in its routing tables.

Using check_snmp in Nagios Core allows automated retrieval of this information...
