mrtg to monitor cpu usage.

[Meni Shapiro]

Hi,

I'm tying to monitor cpu usage on my debian box (PII -350) with mrtg.
I'm using ssCpuRawIdle and i get the graph fine!!
Problem is i get a full graph since the cpu is mostly in idle time and i want to see the usage %....
is there  is simplier way then adding all deltas and dividing by total??? ((cpuUser+cpuSystem+cpuKernel)/(cpuUser+cpuSystem+cpuKernel+cpuIdle))???

thanks,
