Hi Linux gurus!

I am trying to setup some neat cpu monitoring of our Linux servers using snmp, 
all servers are running ucd-snmpd.

I have tried reading cpu idle from 
"enterprises.ucdavis.systemStats.ssCpuRawIdle.0" but this gives an "average" 
value and does not match the accurate value reported by i.e. top.

Does anyone know how to get a "real" cpu idle/usage value using ucd-snmpd?

Best regards

Mathias Kanstrup
