The Java Application Monitor (JAMon) is a free, simple, high performance, thread safe, Java API that allows developers to easily monitor production applications. JAMon can be used to determine application performance bottlenecks, user/application interactions, track application scalability, and more. JAMon 1.0 gathers aggregate performance statistics such as hits, execution times (total, average, minimum, maximum, standard deviation), as well as concurrency information such as simultaneous application requests.
