All Implemented Interfaces:

public class YamlTimeWeightedDeltaEnricher<T extends java.lang.Number>
extends AbstractTransformer<T,java.lang.Double>

Converts an absolute count sensor into a delta sensor (i.e. the diff between the current and previous value), presented as a units/timeUnit based on the event timing.

For example, given a requests.count sensor, this can make a requests.per_sec sensor with DELTA_PERIOD set to "1s" (the default).

Suitable for configuration from YAML.
