Nagios Plugins (Official)

The Nagios Plugins Development Team maintains a bundle of more than fifty standard plugins for Nagios and other monitoring applications that use the straightforward plugin interface originally invented by the Nagios folks. Each plugin is a stand-alone command line tool that provides a specific type of check. Typically, your monitoring software runs these plugins to determine the current status of hosts and services on your network.

Some of the provided plugins let you check local system metrics (such as load averages, processes, or disk space usage), others use various network protocols (such as ICMP, SNMP, or HTTP) to perform remote checks. This allows for checking a large number of common host and service types.

In addition to the core plugins bundle, we maintain a Perl module that makes it easy to write your own plugin. We also take care of an SNMP MIB used for traps sent from Nagios, and of the Nagios Plugin Development Guidelines.
