Class RulesChronoChartRecorder

java.lang.Object

org.kie.api.event.rule.DefaultAgendaEventListener

org.droolsassert.RulesChronoAgendaEventListener

org.droolsassert.RulesChronoChartRecorder

All Implemented Interfaces:

EventListener, org.kie.api.event.rule.AgendaEventListener

public class RulesChronoChartRecorder
extends RulesChronoAgendaEventListener

Collect live performance statistic for rules (then block) as aggregated result and jfree chart TimeSeries.
Suitable for real environment and statistic delivery at the end of the flow or exposed by rest API etc.
Statistic domains are JVM global, you can use unique session prefix as a namespace if needed.
Note: This class creates single background thread (for all instances) which will stop gracefully when last instance will be garbage collected.
