RE: Re: Tracking cpu usage on application instances with JOnAS

I saw this functionality in JOnAS 5 but unfortunately, our applications are running on a JOnAS 4 instance.
I will consider to move to JOnAS 5 as soon as I can.

Thx

You might try to use the new audit feature in JOnAS 5.2.0 M2 which provides a call tree for each request with detailed information such as the response time.
The tool helps the developer to identify the bottleneck in the application and the heavier methods.

Hello JOnAS users,

We have a JOnAS instance running some EAR, WAR applications (about 10-15) and we noticed that Jonas JVM wastes 50% cpu. (100% on one core on a dual-core)
We know that's probably because of one of our application but there is no way to track down the application which spends too much CPU.
Is there a tool (provided by JOnAS or not) which can help us to track this ?

Thanks,

Cordialement,

Anthony BOUQUET
