Interface CollectionStrategy

All Known Implementing Classes:

CentralizedCollectionStrategy, LocalCollectionStrategy

public interface CollectionStrategy

InfraRED uses 2 collection strategies for aggregating the performance statistics - remote and local. For either strategy, the statistics object collected at StatisticsCollector is merged with the global Statistics object held in StatisticsMgr. StatisticsMgr is located remotely wrt the target application, in case of remote collection strategy necessitating the use of BufferedAggregator and Periodic Flush Policy. A collection strategy groups an aggregator, forwarder & flush policy. This is to make sure that only compatible versions of each are used together.

Method Summary

boolean	collect(Statistics stats) Needs to hanle the collection of statistic objects.
boolean	destroy() Destroy the strategy, bring the flush policy etc down.
boolean	init(MonitorConfig configuration) Initialize the collection strategy, this methods need to be overridden to create the aggregator, forwarder & the flush policy and tie them together
void	resume() Resume statistics collection
void	suspend() Suspend statistics collection
