A good tool for gathering system performance numbers (among other 
things) is Munin (blatant plug, the company I work for did the base 
development).

Munin is a GPL'ed, plugin based system for measuring almost anything, 
and somewhat resembling mrtg.

We use it to gather data for several hundred computers we manage for 
various customers, and I find it really useful.

Standard plugins include vmstat, iostat, cpu, memory, network and things 
like counting processes, email queues. In addition there are plugins for 
things like JVM heapspace usage, temperature readings, spam/ham 
distribution, top-ten-virii etc.

The project web site is http://munin.projects.linpro.no/ and a live demo 
is available at http://munin.ping.uio.no/
