Pool Stats

Every so often I get a "the application is performing slowly and we think the LB isn't distributing load correctly", which is miraculously fixed by restarting their app on one of the servers in the pool, yet they never seem to stop blaming the LB. :-) They also never seem to understand that we use persistence too. What I'm trying to determine is there a way to see how many users are connected to each server in the pool. I know, with persistence, it's very likely that one server will have more load than another. When this 'issue' cropped up yesterday, I looked in the GUI at the pool stats and saw 3 current connections to this pool, 1 current connection to pool member 1 and 2 current connections to pool member 2. I told the business owner that and he did not believe that only 3 people were using this app at that particular time. Hence my trying to figure out a way to see how many users were actually connected to the pool and how many were on each server in the pool (there are 2 servers in this pool).
