Added a simple RSS/2.0 feed to GrabPERF tonight: http://www.grabperf.org/grabperf.rss
Provides the Top/Bottom 20 for the last one, six, twelve and twenty-four hours. Subscribe to the feed and when you click on the links, you will see the tables appear. Not brilliant, but functional.
I will build a list of sites currently monitored by the system when I have some downtime this week.
