Both rrdtool and cricket are very useful tools. We use cricket here to keep track of network traffic which is just one small section of its capabilities. It is much easier to use cricket than to hand-roll all your own snmp monitoring stuff. The one thing I would say is that cricket always seems to be more geared towards monitoring devices (like switches and routers) than computers.
