[Wrapper-user] Wrapper and jvmstat

[Hazelton, P. <PHa...@fn...>]

Hi

Has anyone had experience using jvmstat (from Sun's CoolStuff:
http://developers.sun.com/dev/coolstuff/jvmstat/) with an application
started using wrapper?

Basically, an application which you want to monitor using jvmstat should
be started with the JVM option -XX:+UsePerfData.

I've tried adding

wrapper.java.additional.4=3D-XX:+UsePerfData

to my wrapper configuration file, but this seems to have no effect. I
can see the java process I want to monitor in the Task Manager, and
using

wrapper.java.pidfile=3D

confirms that I am looking at the correct java process. However, jvmstat
cannot connect to it.

Any ideas?

Thanks
Paul
