[rrd-users] Using RRDTool & SNMP to graph CPU usage

[Graeme Donaldson]

Hi

I'm trying to figure out how to graph CPU usage percentages with RRDTool. 
I'd like to separately graph User, Nice, System and Idle percentages.  I
think I know which OIDs to monitor (ssCpuRawUser.0, ssCpuRawNice.0, etc),
but I'm not sure what they represent and how to calculate usage
percentages from them.

Has anyone done this before?

Thanks
Graeme
