Hello all,
I need to grab all the information/statistics after firing all the rules. It
is observed that the same can be achieved by different event listeners in
drools. But I don't want to use listeners, instead I need all the
information after firing all the rules. Going through the Drools API, I came
across an interface DroolsManagementAgentMBean which can provide the above
information. I tried to google out the way we need to implement this
interface but in vain.
can any one please let me know how can I achieve the above without using
listeners and at the same time how can I use DroolsManagementAgentMBean?
Thanks in advance,
Asutosh

There is an implementation of the interface
KnowledgeSessionMonitoringMBean,see
./drools-core/src/main/java/org/drools/management/KnowledgeSessionMonitoring.java.
Looking at this implementation will show you that the information
about firing rules, fact operations is collected by the object acting
as a listener.
What's wrong with listeners?

Hello Laun,
Thanks for the reply.
Well there is nothing wrong with the listeners. The requirement is such that
we need all the information only after firing the rules. The
KnowledgeSession itself should provide all the information rather than going
through each and every events and logging the information every time.
Further I am using Drools 5.1.0.M1 API for the current requirement which has
only API (jar files). No source code is available for the same. The
implementation class of KnowledgeSessionMonitoringMBean i.e.
KnowledgeSessionMonitoring.java is not available in Drools 5.1.0.M1 API.
Can you please guide me how can I create an instance of
KnowledgeSessionMonitoringMBean or any other calls which can provide me the
above information.
Thanks in advance,
Asutosh

Just get some version and modify it according to your needs. Here is the
latest:
http://fisheye.jboss.org/browse/JBossRules/trunk/drools-core/src/main/jav...
It's really no big deal to write an agenda listener that counts creations,
cancellations, firings in a map with the rule name as its key. Less than 100
lines of Java code...

All,
The MBeans in Drools where designed to be used out of the box, so no
facilities where implemented to make it easier to re-implement them (of
course you can do that, just saying, try out of the box first and see if it
matches your needs or not... :) ).
To enable the mbeans:
KnowledgeBaseConfiguration conf = ...
conf.setOption( MBeansOption.ENABLED );
