 The Monitor plugin has been around for well over a decade.  This very old plugin has recently gone through major recent enhancements through it's lifetime.  The version of Monitor included with Cacti 1.0 is almost unrecognizable from earlier versions of the plugin.  It's is essentially a finished project, though if there are any feature requests, we won't push them away.
