I am intressted in methods to do (non intrusive) performance profiling in a Spring application deployed in a Java EE server. In my case I use WebSphere Application Server 7, WebSphere MQ 7 and OpenJPA/IBM DB2.
I only need a brief overview of potential bottlenecks etc. I could always log time stamps and do some analysis, but if you guys have any best practice, I am listening!
I recommend the VisualVM profiler. It ships with modern Sun/Oracle JDKs (
bin/jvisualvm.exe) and is able to connect to running java instances.More information can be found here: http://visualvm.java.net/profiler.html
