public class Increase extends TimeSeriesAggregateFunction implements OptionalArgument, ToAggregator
The increase() function calculates the absolute increase of a counter field in a time window. It is similar to the rate() function, but instead of calculating the per-second average rate of increase, it calculates the total increase over the time window.
