David, Just my two cents - check out Cacti. It comes with lots of pre-loaded RRD/RRA definitions, among them being the process counts. Of all the frontends to RRDTool, I prefer Cacti over Munin, Cricket, MRTG, and the like. The documentation is a bit less than you'd like, but once you get your head around it it's really a dream to work with.
