=head1 NAME
monit_parser - Monit status parser plugin for munin.
=head1 APPLICABLE SYSTEMS
Any system running monit.
Monit needs to be configured with the httpd port enabled, e.g.:
set httpd port 2812
The configured port is not important, since this plugin uses "monit status"
for retrieving data. Thus the monit configuration is parsed implicitly.
=head1 CONFIGURATION
This plugin requires read access for the monit configuration.
Thus it needs to run as root:
[monit_parser]
user root
