<div><br></div> That works. Just FYI, the same data is available through the Drools MBeans... you can use jconsole to monitor it or any other JMX console.<div><br></div><div> Edson<br><br><div class="gmail_quote">2011/10/12 Dean Whisnant <span dir="ltr"><<a href="mailto:dean@basys.com">dean@basys.com</a>></span><br>
<blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex;">You could create a listener and combine it with a log. There is org.drools.event.rule.DefaultAgendaEventListener that has two methods I use to log which rule started firing and when the rule completes firing with:<br>
<br>
@Override<br>
public void beforeActivationFired(BeforeActivationFiredEvent event)<br>
{<br>
try<br>
{<br>
logFile.write("Package(" + event.getActivation().getRule().getPackageName() + ").Rule(" + event.getActivation().getRule().getName() + ") firing ... ");<br>
}<br>
catch (Exception e) { }<br>
}<br>
<br>
@Override<br>
public void afterActivationFired(AfterActivationFiredEvent event)<br>
{<br>
try<br>
{<br>
logFile.write("done!\n");<br>
}<br>
catch (Exception e) { }<br>
}<br>
<br>
You could obviously do other logging with time and date stamps, or send it to a database rather than a .log file like I'm doing here. In my case I get a list of all rules that fire in a fireallrules session. I can see if a rule fires multiple times, or ends up in an endless loop.<br>

Subject: [rules-users] How to improve drools performance?<br>
<br>
Is there a way to log / monitor the time taken for rule in a Drools rule set?<br>
<br>
Is there a way to make sure that one rule is not executed more than once(It seems to be happening in my case)<br>
<br>
What are the general guidelines on improving Drools performance?<br>
<br>
Currently I am using a one single DRL file with 100 odd rules.<br>
<br>
Any additiional information you need will be provided.<br>
<br>
Thanks,<br>
<br>
