+monit_parser -  Monit status parser plugin for munin.
 
-STATUS_CMD = "monit status"
+
+=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
