This is ok, if you have a always increasing value like an interface couter, but it's IMO not ok, if I have a per-calutlated value, that I give to mrtg. I tell just this to mrtg by setting the option gauge. Take my example: The CPU has had a usage (for usr-processes) of 68% over the last 5 minutes. So even if the measurement interval is exactly 4 min 50 sec or 5 min 10 sec, the usage in the last (exact) 5 min is probably 68%. It is probably not 65% and probably not 71%. I just would like mrtg to graph exactly the value I hand over to it, with no interpolation. Is this impossible? Would it be an idea to introduce an other option - lets say "nointerpolation" or so - that tells mrtg to do no interpolation? I think there must be a lot of other people who would like to graph e. g. their CPU or other pre-calculated values. Freundliche Grüße i. A.
