Nagios::Plugin — Nagios Development for the Lazy!

Ah, very handy: a Perl module to help quickly write Nagios plugins. From the webpage:

Nagios::Plugin::Getopt is an OO perl module providing standardised and simplified argument processing for Nagios plugins. It implements a number of standard arguments itself (–help, –version, –usage, –timeout, –verbose, and their short form counterparts), produces standardised nagios plugin help output, and allows additional arguments to be easily defined.

It consists of

Nagios::Plugin::Getopt

Nagios::Plugin: A family of perl modules to streamline writing Nagios plugins
Nagios::Plugin::Config: read nagios plugin .ini style config files
Nagios::Plugin::ExitResult: Helper class for returning both output and return codes when testing.
