This is mine ;-) Try the last version on my branch. 
This plugin work fine in a large environment (5300 server and more than 19000 update by second in MySQL) but never tested on Solaris.

Are you using Perfwatcher too ? A friend of mine is currently writing a plugin to do aggregation of metric directly in Collectd if this is the subject.
