CPU utilization is always defined with the data-type gauge. A object is referred with the data-type gauge when it can increase and decrease but will not exceed it maximum value Processor load,memory,disk usage are defined with the data-type gauge. Counter is used when the object is monotonically increasing and will not decrease until the agent is rebooted.This data-type is used for variables like in and out traffic,errors or discards on a interface.
By default MRTG treats a variable as a counter and since counters are always a increasing value MRTG polls the variable and subtracts the current value it receives with the previous value it received during the last poll and divides it with the time elapsed since the last time it polled the device(with the time interval you specified in your daemon or cron tab) So if you want to declare the variable specifically with the data-type gauge then you need to use make use of the options field in your cfg file..... option[xxx]: gauge Now, MRTG will treat the object as gauge and will only graph the instantaneous value it receives during the current poll. If you are still unable to understand what i said go through mrtg command-reference . There is also an cfg example for monitoring cpu load of a cisco router under mrtg-nt guide documentation.

I have set MaxBytes to 10000. The graph is showing utilization value as 700 (I have not set Factor[vodclb01-mn-cpu]: 0.01 ). This oid is of type gauge32. I thought that it returns % CPU utilization. But, I was wrong. Could you please let me know what type of values gets stored in gauge32 or how CPU utilization gets collected in gauge32 variable? I am bit confused!
