Re: [rules-users] Time Sliding Window Question

Hello, I am fairly new to Drools and tried my first steps with Drools Fusion and was running into the following problem: According to the Drools Fusion User Guide Version 5.4.0.Final on page 32 the following pattern should work and select events in between the last 10 minutes: ... StockTick() over window:time( 2m ) ... I tried the following example, simulating RHQ EventComposite Events with a simple Junit test: ... KnowledgeBuilder kbuilder = KnowledgeBuilderFactory.newKnowledgeBuilder(); kbuilder.add(new ClassPathResource("rhqrules.drl", getClass()), ResourceType.DRL); KnowledgeBaseConfiguration config = KnowledgeBaseFactory.newKnowledgeBaseConfiguration(); config.setOption(EventProcessingOption.STREAM); nowledgeBase kbase = KnowledgeBaseFactory.newKnowledgeBase(config); kbase.addKnowledgePackages(kbuilder.getKnowledgePackages()); KnowledgeSessionConfiguration conf = KnowledgeBaseFactory.newKnowledgeSessionConfiguration(); conf.setOption(ClockTypeOption.get("pseudo")); ksession = kbase.newStatefulKnowledgeSession(conf, null); ... inside the test method: ... For-Loop inserts new Events and increases the pseudo clock in one minute steps: ... for (int i = 0; i < 100; i++) { timestamp = clock.advanceTime(1, TimeUnit.MINUTES); ksession.insert(new EventComposite("EventDetail" + i, resourceId, "resourceName" + i, "resourceAncestry" + i, resourceTypeId, eventId, severity, "sourceLocation" + i, timestamp)); } ... ksession.fireAllRules(); ... The .drl definition should fire only events of the last 10 minutes, however all inserted 100 events are fired: declare EventComposite @role( event ) end rule "Rule1 events in between last 10 minutes" when $event : EventComposite() over window:time( 10m ) then System.out.println("Event in between the last 10 minutes:: " + $event); end On the other hand this rule works as expected and selects only events older than 10 minutes: rule "Rule2 events not in between the last 10 minutes" when $eventA : EventComposite( ) not EventComposite( this.resourceId == $eventA.resourceId ) over window:time( 10m ) then System.out.println("Event not in between the last 10 minutes: " + $eventA); end My question is: What did I wrong in the definition of Rule-1, what is the correct statement for finding the last 10 minutes events? Background information: I am doing some research on implementing using the drools framework inside the RHQ framework for complex event processing. I would like to show that this is possible and could be uses reasonable for RHQ event processing. Any help is highly appreceated!
