Hi All,

Is there is an easy way to check how many "simultaneous client sessions" are active in BOS?
 
Thanks
Seb

Looking into it. My suspicion is that this is an IIS thing but I can think of some simple instrumentation you could add that might work as well. Stay tuned.

Well, not only for clients connected to BOS hosted in IIS, but also Windows Service BOS (ServerServices.exe or ServerConsole.exe)

Thanks
Sebastian

The BOS does know the number of active users (as we count them) but does not expose that number today. We are looking at adding a feature to make that number available.

You can track who/how many users login and logout by implementing the IEntityLoginManager. No obvious way to decrement the count when someone just hangs up or crashes. We "time out" inactive users (after 30 minutes by default) but we don't tell you when.
 
You can guess when folks are timed-out. But that means keeping your own session table (hooking login/logout) and monitoring activity through the other interceptors so you can "time them out" yourself. I wouldn't want to have to do this myself.
 
Hope you can hang in there while we think of something.
