On *ix (e.g., Aix, Unix, Linux), I would use something like lsof to query the operating system for the active connections to the AppServer ports.

Question
How to count the amount of open sessions on Webshere
Hi experts,
I support a solution that inlcudes an IBM Websphere 6 application server. I wish to count the number of live/open/active sessions open on the application server. How do I achieve this?
Basically I want to know how many users are active on the server.
Preferable, the method needs to be as easy and quickly as possible so that I could task a very junior resource to check and monitor the session count every 30 minutes or so.
Thank you

How accurate a measurement do you need?
- Really accurate?
Change your application to count & track active sessions
- Accurate?
You could use the Performance Monitoring Infrastructure (PMI)
http://publib.boulder.ibm.
to analyze all sorts of stuff going on in your AppServer.
