I am not sure, that I understood your question.
What do you want get displayed? Only the difference from one reading to
the next or the absolute value of the reading?
For the difference: use no option, this is the default behaviour
For the absolute value: use "Options[xxx]: gauge" in the config for this
It would be easier to answer, if you post the few interesting lines of your
mrtg.cfg here. Then we all here can read, what you did.
