Hi, I have a situation where I am not sure what to instruct MRTG/RRD as the "type" of the expression.
Rather than give you the custom instance, I will give you an illustration based on the MIB-2 "if" objects so its easier for you to understand my problem. If for instance, I wanted to instruct MRTG, or RRD, to plot the percent utilizaton of a network interface (I know MRTG internally does this specific case, but just assuming it did not), Then I would make up a "target expression" like ((ifInOctets[ifIndex] + ifOutOctets[ifIndex]) * 8 / ifSpeed[ifIndex]) * 100 But unfortunately, both ifInOctest and ifOutOctets are MIB counter objects (their values keep increasing). So although the resultant value of this expression should be a guage (because percent utilization for the interface keeps incrementing and decrementing), I have to set the type for this target expression as an MRTG counter. But still it is incorrect, because when I label the expression as an MRTG/RRD counter, MRTG/RRD tracks the value as a "RATE" (difference in seconds) : which again makes the value being graphed incorrect. So how do you suggest I graph such expressions using MRTG or RRD, which have MIB counter objects, but the resultant values from the expression itself is NOT a rate?
