You should monitor the datasource pool, here you might use twiddle. Another way is to set a hard limit in a test environment, <blocking-timeout-millis> == 0 you will get an exception instead of slow down the application because of connection bottleneck.

Other canidate will be the GarbageCollector, here you can use the standard gc.log see

For your application you migth use the admin console wich shows the number of calls and some statistics about your EJBs.
Also some general statistic logging within the application si helpful.
But all of this depends the structure of you app (JSP, EJB .....)
