ganglia for fun

I have been playing with ganglia [ http://ganglia.info ] for the last few days on 1/10 of our 200 server web cluster at work.  While I see many useful metrics I am having trouble really getting solid numbers.  Maybe over time it will level out to the point that changes can be see but for not the information does not seem more useful then our zenoss [ http://www.zenoss.com ] install.

Also I had some trouble with the install not showing all data on the member nodes when I self compiled so I wound up using the rpms from fedora epel.repo which worked like a charm.
