Have a look at the AgendaEventListener. You can use these callbacks to see which rules fire and information about them<br><br><table summary="" width="100%" border="1" cellpadding="3" cellspacing="0"><tbody><tr class="TableRowColor" bgcolor="white">

@ll,<br>I have a question regarding the possibilities to monitor and report on the rules activity.<br>I have seen that with Drools Guvnor, it is perfectly possible to monitor scenario's, see what rules fired, etc.<br>
<br>
Now, going further, I have two questions:<br>- Is it possible to monitor rule activity (which rules got fired etc) in a production situation. Eg. Is it possible to start recording activity at some time until a proble occured and to review the logs afterwards. This would be of use when scenario's are not covering all possible cases.<br>
- Is it possible to produce reports on rules, usage of rules (eg. what rules are fired and what rules were fired most), performance, ... <br>And if not, what could be a good starting point to create them ?<br><br>My experience with Drools is rather limited. Let's say that I am interested in expert system and technologies surrounding it. At this moment I am getting a 'theoretical' grip on Drools and its possibilities (of course, I couldn't help also creating some kind of poc :) ).<br>
