[mrtg] Need help on CPU info collection

[Steve Shipway]

You are using the wrong counters.

Either use ssCpuUser, ssCpuSystem and ssCpuNice (which return values in percentages) with the 'gauge' option and a MaxBytes[] of 100, or else use ssCpuRawUser etc WITHOUT the gauge option but with a Factor[]:100 (as these return a total count of seconds used, so rate of change per second of total seconds used x 100 = percentage use).  Your SNMP agent may not support both though.

I can still not generate the CPU graph after adding GAUGE to my config.
I really have no idea now. The CPU graph generated by MRTG is not all 'zero's, after I zoom the graph and seeing it careful, it doesn't generate CPU statistics at all.
