Cacti.... also discovered Zenoss today (www.zenoss.com), looks very cool, not sure what data it shows yet, still looking into it.

Graphs/stats plus monitoring, with the ability to finely tune monitoring rules to your specific needs without a headache.
If you're interested, PM me and I can provide you with some screenshots of what it looks like for my environment.
