I'm getting some odd results when running Pulse against the latest PA build (2.0.3), where Pulse is over-reporting the number of actual users, presumably because of some different way the threads are working. The screenshot attached actually has only one admin user logged on.
The list that you are looking at is what the TM1 top API is feeding pulse. I believe this could be due to the internals of PA and how is managing its connections to the TM1 server.
Thanks for pointing this out,
