Subject Re: Jmxproxy issue
Date Wed, 19 May 2010 10:27:11 GMT
>From what I know, you do not get detailed memory information on the jmx
proxy servlet without the JMX agent enabled.

You can enable it by adding the following JVM argument.
-Dcom.sun.management.jmxremote

I have tested this on Tomcat 5.5.27 with Java 1.5.0_14. With the above JVM
argument added to the Tomcat process you get detailed memory information
including Garbage collections stats on the jmxproxy servlet.

Hope this helps.

Anurag
