[rules-users] Get statistics of the rule engine

Hi, for a frontend I am developing, I would like to show statistics about the rule engine: things like uptime, memory used, current number of facts, and the running rule packages: how many times a rule was fired and so on... I am using Drools 4. Do you know if there a way to get this kind of statistics ? By the way, thank you all, I learned a lot following this list :) Julien Nicoulaud Bull SAS
