Subject Re: tools to measure average concurrent users?

Another idea If you want to calculate this going forward, you could
simply use the %T for a custom access log in apache.

%T gives you the total time it took to service a request.  From there
it should be trivial to parse that access_log and determine
concurrency at any point for any URL.

We have a JBoss running several apps, so it's necessary to filter by app.
