hmm that's true.. I am still confused by 
the whole thing.. So you set the "gauge" option 
so mrtg doesn't divide by the elapsed time?

I guess adding up all the kernel ticks including idle time 
will give total ticks..  allowing to generate a 
relative percentage of time spent in each tick type.
Which is basically what cpu usage % is.. I guess..
