JMSTester online

The last couple of weeks I have spent some time on site working with ActiveMQ users helping them to get a decent benchmark in place for their JMS layer. I already had some code for a JMS benchmarking framework from earlier assignments and used the chance to get that a bit polished and documented.

Essentially it is designed to run a set of distributed JMS clients with a defined load profile. The framework will then measure the throughput and also allows to measure key performance indicators via JMX or on the OS level during the benchmark. This gives nice hints, whether the JMS server machines are CPU bound, lack IO capacity or have to less memory etc.

For all metrics graphs are created and if you want to run even more sophisticated analysises, all metrics are pushed into a CSV file that can be used in your favorite spreadsheet calculator.

The JMSTest framework is now a public project at FUSE Source.

Have fun trying it out if you want, any feedback is more than welcome.
