Ciao, not really sure where is your problem exactly, but as I use often similar use-case of yours, thought worthy to share what I usually find useful: 1. check STREAM mode is activated 2. check in the .drl is clearly defined what is a Fact, and what is an Event. In your case I would check TemperatureRead is declared as Event? 3. activate Audit log / runtime logger. I find especially useful point #3 because you will see, as the session clock advances, what is still in working memory and when rule is activated you will see against which Event/Facts. Hope this is helpful Ciao MM On Fri, Dec 6, 2013 at 11:54 PM, martinzp <martinzp(a)gmail.com&gt; wrote: > Hi, i am new in the forum, and a beginner user of Drools so forgive me if > my > question isn't quite good. > > I want to test the "over window:time" operand. > > In order to do that i use the pseudo clock, but i have noticed that it > doesn't behave as i would expect. > > The behaviour i think i observed, is that the rule is using the real clock > instead of the pseudo clock. > > *Here is my drl file:* > > rule "Fire Detected" > when > c : Number(intValue >= 3) from accumulate ( > $tr : TemperatureRead(read > 40) > over window:time ( 1s ) > from entry-point entryone , > count ($tr) > ) > then > System.out.println("Fire Detected!"); > end > > > > *and here is the portion of my main file that inserts the events:* > > TemperatureRead temp1 = new TemperatureRead(33.2); > TemperatureRead temp2 = new TemperatureRead(38.7); > TemperatureRead temp3 = new TemperatureRead(39.5); > TemperatureRead temp4 = new TemperatureRead(42.5); > TemperatureRead temp5 = new TemperatureRead(43.1); > TemperatureRead temp6 = new TemperatureRead(47.8); > > SessionPseudoClock clock = ksession.getSessionClock(); > > entryPoint1.insert(temp1); > > clock.advanceTime((new Date()).getTime(), TimeUnit.MILLISECONDS); > > fireRules(); > > entryPoint1.insert(temp2); > > clock.advanceTime(1, TimeUnit.SECONDS); > > fireRules(); > > entryPoint1.insert(temp3); > > clock.advanceTime(1, TimeUnit.SECONDS); > > fireRules(); > > entryPoint1.insert(temp4); > > clock.advanceTime(1, TimeUnit.SECONDS); > > fireRules(); > > entryPoint1.insert(temp5); > > clock.advanceTime(1, TimeUnit.SECONDS); > > fireRules(); > > entryPoint1.insert(temp6); > > fireRules(); > > > > > > In my opinion, the rule shouldn't be fired, because as i am (supposedly) > using the pseudo clock, the events shouldn't fall into the same sliding > window (1 second.) > > In general, the rule should fire when it detects 3 or more temperature > reads > with a temperature over 40. > > Any idea about what i might be doing wrong? > > Thanks in advance! > > > > > > > > -- > View this message in context: > http://drools.46999.n3.nabble.com/Problem-with-time-sliding-windows-and-p... > Sent from the Drools: User forum mailing list archive at Nabble.com. > _______________________________________________ > rules-users mailing list > rules-users(a)lists.jboss.org > https://lists.jboss.org/mailman/listinfo/rules-users > _______________________________________________ rules-users mailing list rules-users(a)lists.jboss.org https://lists.jboss.org/mailman/listinfo/rules-users
