public class RateAggregator
Aggregates the rate at which statistical events occur. May be deployed as a node singleton or a non-singleton.
2 Targets Required in this order:
-- SDCounterDescriptor for Cumulative Rate
-- SDCounterDescriptor for interval Rate
2 dependencies required in this order:
-- SDCounterDescriptor containing the integer value (event) for which a rate will be calculated
-- SDCounterDescriptor Run/Run Duration/Scalar cumulative
An example of this Aggregator deployed as a node singleton follows:
Note: When RateAggregator is deployed as a node singleton as shown above, the "Rate interval" and "Rate For Run"
counters are automatically created and filled for each individual target such as Page or Page Element. It
is not necessary to deploy an aggregator to calculate these individual target counters if a node-singleton
is already using the target as a dependency.
