Decision manager -Analytics and importing and viewing latest facts

Hi,

I am currently working on Redhat decision manager prototype.

1)Is there any analytics to understand how many times the rules have been run in Decision manager in PROD environment.

2) can I see the ingested data means fact for which rules are applied. mean if I apply rules on 100 records of person object .can I see them in the Decision manager

3) We use person object as data model.. and use the REST call to apply rules
what if there are few more columns added to the person object, can that be imported automatically and rules applied on these columns.

Also, the same question applies to projects using the Drools workbench as well
I am comparing a few products for decision manager, Some of the other products give this ability but i am favoring Redhat

Kind Regards
