I've been using MRTG for ages to monitor cpu load and happily recommend 
it for all manner of monitoring (not just routers 8^).  MRTG can be 
found at:
http://oss.oetiker.ch/mrtg/index.en.html

...and the program to pass cpu load to mrtg can be found at:
http://oss.oetiker.ch/mrtg/pub/contrib/linux_loadavg_mrtg.tar.gz

...my mrtg.cfg for this bit
