Stopwatch
· Stopwatch is a free, simple, highly extensible, Java API that allows developers to easily monitor
whole application or any part of it. By default Stopwatch generate reports about hits, execution
times (total, average, minimum, maximum) as well as load but it can be easily extended to measure
anything else by providing custom engine. Out of the box Stopwatch uses an in-memory HSQL database.
It is able to persist collected data using a "storage". There is "storage" provided to persist into
HSQL database and custom "storage" can be easily integrated.
