Thanks for the quick reply. Yes, the original facts are already coming in via a stream (Fusion) to an existing set of rules so I was hoping to build on that. What I am trying to do is evaluate logins information as users are attempting to login trying to identify hack attempts by a person trying to login with a slightly different user name over a given period of time.
