I'm also releasing something called cpupie. It uses the tkpiechart
widget and scotty and tclx to monitor the CPU loads of any unix
servers you specify. It uses that rstat RPC call to get the CPU
load and calculate the pie slice sizes. We use it to monitor performance
on our servers.
Both are available at ftp.eng.auburn.edu:pub/doug/
