jvmstat with JBoss

[rafcio]

Hi,

I try to use jvmstat

E:\data\rafcio\bin\jvmstat\bat>visualgc.cmd
invalid argument count
Version 3.0_b04 10/12/04 - Requires J2SE/Hotspot 1.5.0 or later

with my remote JBoss installation under Linux. The parameter is set to:
JAVA_OPTS="$JAVA_OPTS -XX:+UsePerfData"

and we use this Java:

[12:25:35 ofadevel@ofatest1:ofadevel]$ /usr/oma/java/bin/java -version
java version "1.4.2_07"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2_07-b05)
Java HotSpot(TM) Client VM (build 1.4.2_07-b05, mixed mode)


I get this error message:

E:\data\rafcio\bin\jvmstat\bat>visualgc.cmd 31159@10.11.0.29
RMI Registry not available at 10.11.0.29:1099
Connection refused to host: 10.11.0.29; nested exception is:
java.net.ConnectException: Connection refused: connect

I tryied to start JBoss 3.2.5 unter 1088 instead of 1099. A local installation unter Windows XP works fine.

What can I do? has anybody use jvmstat with remote JBoss?


Best Regards,
Rafal

From what you've written, it appears that you are trying to run this with a 1.4 JVM, and yet the error message is reporting that you need hotspot 1.5.

I think you'll need a 1.5 JVM for this (i.e. you need to install J2SE 5.0).

I have had success with it by running visualgc local to the server. Visualgc should be run with JDK1.5. Jboss need not run JDK1.5. set your environment variable..
JVMSTAT_JAVA_HOME = C:\Progra~1\Java\jdk1.5.0_05
and
PATH to include :\Progra~1\Java\jdk1.5.0_05\bin;c:\jvmstat\bin

Hope that helps..
