RE: Réf. : Tracking cpu usage on applic ation instances with JOnAS

Sorry for the missing informations,

JOnAS	:4.10.3
JDK 	:1.5 Sun
OS 	:Windows server 2003

I didn't know that java profilers could track cpu usage, in fact I used this only for memory usage to catch a snapshot of a memory.
I will look in this direction, thanks

Hello Anthony,

Could you specify yours:
- jonas version ?
- JVM version (and type: Sun, IBM, Jrockit) ?
- OS ?

Sincerely,

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
