Re: [rules-users] How to monitor what rules are fired
Thanks Michael. Michael Neale wrote: Hi Ravi - if you look at the classes in: org.drools.audit For example: WorkingMemoryInMemoryLogger.java - you can wrap that around a session, and it will accumulate stuff in memory that you can print out. You will want to have good "toString()" methods on your fact objects - so you can inspect the state nicely. But if you are caringly only about rules - take a look at LogEvent - BEFORE_ACTIVATION_FIRE (or the AFTER equivalent) - they book end the firing of a rules consequence - so pick one event type, and count it. (I use that approach in a few places). On Wed, Oct 29, 2008 at 4:42 AM, Ravi Krishnamurthy <[EMAIL PROTECTED]> wrote: Thanks Michael. I will look into it.
