[mrtg] Re: CPU monitoring

[Stieers, Ken]

Daniel, 

I'm assuming that the logs are showing all zeros except for the first line
and you have all zeros on the graphs?  I'm assuming this just gives you the
momentary utilization of the CPU?  This is also a gauge value, so you need
to add "gauge" to the Options line.
