Hey guys,
  I'm trying to graph my cpu usage according to the following tutorial:

	http://net-snmp.sourceforge.net/tutorial/tutorial-4/mrtg/

I have these setup just like in the tutorial, but I am getting wierd 
results:

UCD-SNMP-MIB::ssCpuRawUser.0 = Counter32: 3597620
UCD-SNMP-MIB::ssCpuRawNice.0 = Counter32: 839
UCD-SNMP-MIB::ssCpuRawSystem.0 = Counter32: 19131260
UCD-SNMP-MIB::ssCpuRawIdle.0 = Counter32: 211001445

As such, my graphs are wrong:

	http://cytrex.cytelcom.com/cgi-bin/14all.cgi?dir=asterisk/

If you look at the lower left graph (which is Idle vs User), it doesn't 
even show Idle CPU. It says the number above is NaN.

Any ideas on why I am getting bad data?

This is on a 2.6.11 kernel running NET-SNMP version: 5.1.3.1.

Thanks,
Matthew
