[rules-users] How to identify the single condition(s) of a rule that activate it

Hi all! I\'am using Drools 5 to manage the rules of a click fraud detection system. If one rule is fullfilled the click is marked invalid, but all rules that fire activation should be recorded. I can do so collecting the rule names in a Set. Now I am supposed to record a more fine-grained image of what made a click get marked invalid preferably in a way that every condition is tested however one just fired activation or not. Would be great to be able to store some identifier to each condition. Is there a way to find out which condition made the rule fire activation? I looked at DefaultAgendaListener, but could not find any reference to the single condition(s) that was (were) met but only to the whole rule. Could anyone help me? Thank you, Chris
