Package etm.core.aggregation

Pre-packaged aggregation strategies.

Description

Interface Summary

Aggregate	The Aggregate represents aggregated information of an execution point.
Aggregator	An EtmMonitor uses a instance of Aggregator to collect and aggregate measurement results.
EtmFilter	An EtmFilter can be used to decide whether a given EtmPoint satifies certain criteria or not.

Class Summary

BufferedThresholdAggregator	The BufferedThresholdAggregator wraps an Aggregator instance and prevents processing of every measurement result by buffering them until specified threshold is reached.
BufferedTimedAggregator	The BufferedTimedAggregator buffers measurement results for a certain period of time.
ExecutionAggregate	The ExecutionAggregate represents the aggregated information of an execution point.
FlatAggregator	Deprecated. Use RootAggregator instead.
NestedAggregator	Deprecated. Use RootAggregator instead.
NotifyingAggregator	An aggregator that creates CollectEvents for every new collected EtmPoint.
RootAggregator	An Aggregator that cumulates results, supports both nested and flat aggregation.

Package etm.core.aggregation Description

Pre-packaged aggregation strategies.

Usually aggregation of execution statistics is computational intensive. Therefore collected data should be flushed using a background or bulk processes, which will be encapsulated by so called Aggregators.

This package contains basic aggregators and the related interface.
