When looking at lengthy traces with thousands and millions of messages (trace statements) we can see regions of activity where statement current (Jm, msg/s) is much higher than in surrounding temporal regions. Hence the name of this pattern, Activity Region. Here is an illustration for a typical ETW/CDF trace where a middle region of activity (Jm2) signifies a system performing some response function like a user session initialization and application launch:
