How to get current busy worker threads which are serving clients ?

[GoogleCodeExporter]

What steps will reproduce the problem?
1. I am running with 50 threads when I am having many request at the same time 
server is taking a long time to response. 

What is the expected output? What do you see instead?

Is there a way I can get current working thread thread count which are busy in 
serving other user so I can increase number of thread according to the 
requirement.
