Profiling using OFBiz
Hi,
I need to check memory leaks, memory profiling and cpu profiling with OFBiz.
Can anyone suggest me the best tool for OFBiz profiling...
Can I create core dumps and find cpu usage by OFBiz??
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Thanks & Regards,

Thanks Brett,
Very interesting!

Neha,
I posted this message a few months ago about some profiling probes we wrote
to measure method times. They work pretty well and allow you specify what
you want to profile (e.g. com.mycode.* or org.ofbiz.entity, etc).
I've been meaning to contribute these tools back with instructions on how to
use them. I'll open a JIRA issue when I can get this complete.

We have been experimenting with the TPTP tools from eclipse to find
performance bottlenecks. The tool let's you create your own custom probes
that can be inserted at run time into your deployed application. The nice
thing about these custom probes are they don't create a large footprint like
so many other profiling tools.

RE: Profiling using OFBiz
Posted by Neha Mehta <Ne...@lntinfotech.com>.
Hi ,
Thanks a lot for your replies. I have used Your Kit JProfiler for checking memory leaks in the application.
I find that Delegator, ModelReader and JobPoller objects hold the maximum place in the memory.
But how should I detect memory leak and which OFBiz objects are causing memory leaks??
How should I solve the memory leak probe, if exists???
Kindly help me if there are any documents or steps to perform this.

Hi Neha,
Our team had serious problems with memory leaks for 2 main reasons:
1) Lack of knowledge of the correct use of the Entity Manager.
2) In cases of a large number of request.
We use the tool kit Your www.yourkit.com/java/profiler/ that helped us
Identifying critical points to refactor the source code.

Found jprofiler very effective. though a bit expensive

you can use probe application, which can be started from hot-deploy.
