That's right. You are not working with increments, you are working with rates. The calculation is not (new-old), it is ( (new-old) / (time_new-time_old) ) this is also referred to as delta(value) divided by delta(time). The time component is always there, even for a GAUGE. counter: rrdtool calculates both delta(value) and delta(time). derive: dito, however the rate can be negative absolute: you are feeding delta(value), rrdtool computes delta(time) gauge: rrdtool doesn't calculate delta(value) nor delta(time) The resulting rate (after calculations, if necessary) is subject to normalization (explained further on faq.mrtg.org and in the docs). If you want to know delta(value) this means that you have to multiply by delta(time). This is because ( (X / t) * t ) results in X. This may give you slightly different numbers than those you put in, this is because of the normalization.
