Actually, the difference is the storage of the data. RRDs store
rates, period. With a COUNTER or DERIVE DS, the rate is calculated
based on the difference between the new value and the previous value
and the elapsed time between the updates. With a GAUGE DS, the value
given to rrdtool is assumed to be a rate and stored as is, without
regard to the previous value or the time delta. To my knowledge, this
is the only difference between these DS types.
