Starting and Stopping Event Analytics

When you start the Event Analytics module, all enabled sessions start. For each session, all persisted fact objects are inserted into the stateful knowledge session to preserve the state when the session was stopped. No rules are fired when inserting these objects.

Note: The Event Analytics module will not start if there is an error in a Drools Rules Language (drl) file. So you must not stop Event Analytics when there is an error in a drl file that is active in a started session.

If you get strange Drools errors when starting Event Analytics even though the drl files are okay, try to restart Event Analytics. There is a bug in Drools Expert 5 when running several sessions in parallel.
