<div dir="ltr">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:<div><br></div><div>1. check STREAM mode is activated</div>
<div>2. check in the .drl is clearly defined what is a Fact, and what is an Event. In your case I would check <span style="font-family:arial,sans-serif;font-size:13px">TemperatureRead is declared as Event?</span></div><div>
<font face="arial, sans-serif">3. activate Audit log / runtime logger. </font></div><div><font face="arial, sans-serif"><br></font></div><div><font face="arial, sans-serif">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.</font></div>

question isn't quite good.<br>
<br>
I want to test the "over window:time" operand.<br>
<br>
In order to do that i use the pseudo clock, but i have noticed that it<br>
doesn't behave as i would expect.<br>
<br>
The behaviour i think i observed, is that the rule is using the real clock<br>
instead of the pseudo clock.<br>
<br>
*Here is my drl file:*<br>
<br>
rule "Fire Detected"<br>
when<br>
c : Number(intValue >= 3) from accumulate (<br>
$tr : TemperatureRead(read > 40)<br>
over window:time ( 1s )<br>
from entry-point entryone ,<br>
count ($tr)<br>
)<br>
then<br>
System.out.println("Fire Detected!");<br>
end<br>
<br>
<br>
<br>
*and here is the portion of my main file that inserts the events:*<br>
<br>
TemperatureRead temp1 = new TemperatureRead(33.2);<br>
TemperatureRead temp2 = new TemperatureRead(38.7);<br>
TemperatureRead temp3 = new TemperatureRead(39.5);<br>
TemperatureRead temp4 = new TemperatureRead(42.5);<br>
TemperatureRead temp5 = new TemperatureRead(43.1);<br>
TemperatureRead temp6 = new TemperatureRead(47.8);<br>
<br>
SessionPseudoClock clock = ksession.getSessionClock();<br>
<br>
entryPoint1.insert(temp1);<br>
<br>
clock.advanceTime((new Date()).getTime(), TimeUnit.MILLISECONDS);<br>
<br>
fireRules();<br>
<br>
entryPoint1.insert(temp2);<br>
<br>
clock.advanceTime(1, TimeUnit.SECONDS);<br>
<br>
fireRules();<br>
<br>
entryPoint1.insert(temp3);<br>
<br>
clock.advanceTime(1, TimeUnit.SECONDS);<br>
<br>
fireRules();<br>
<br>
entryPoint1.insert(temp4);<br>
<br>
clock.advanceTime(1, TimeUnit.SECONDS);<br>
<br>
fireRules();<br>
<br>
entryPoint1.insert(temp5);<br>
<br>
clock.advanceTime(1, TimeUnit.SECONDS);<br>
<br>
fireRules();<br>
<br>
entryPoint1.insert(temp6);<br>
<br>
fireRules();<br>
<br>
<br>
<br>
<br>
<br>
In my opinion, the rule shouldn't be fired, because as i am (supposedly)<br>
using the pseudo clock, the events shouldn't fall into the same sliding<br>
window (1 second.)<br>
<br>
In general, the rule should fire when it detects 3 or more temperature reads<br>
with a temperature over 40.<br>
<br>
Any idea about what i might be doing wrong?<br>
<br>
Thanks in advance!<br>
