I am new to this forum and also to Ganglia - We are trying to capture JVM metrics through Ganglia - I have followed the steps through this link - https://github.com/ganglia/jmxetric

High Level - Installation

Unzip the archive Add the following to your JVM

java -javaagent:<path>/jmxetric.jar=host="",port="",config="",process="" 
usual.java.main.class

Demo / Quickstart

This example works for version 1.0.6 of jmxetric and gmetric4j.

  1. Ensure you have a gmond running on localhost:8649

    $ pgrep gmond # should return a valid PID
$ nc localhost 8649 # dumps some XML to stdout

  2. $ git clone same link as above

  3. Download jmxetric.jar, gmetric4j.jar and oncrpc-1.0.7.jar all into the same directory.

  4. $ cd jmxetric

  5. In bash do:

    $ export config="host=localhost,port=8649,wireformat31x=true,config=etc/jmxetric.xml"
$ java  -Djava.util.logging.config.file=etc/logging.properties \
    -cp gmetric4j-1.0.6.jar:oncrpc-1.0.7.jar:jmxetric-1.0.6.jar \
    -javaagent:jmxetric-1.0.4.jar=$config info.ganglia.jmxetric.JMXetricAgent

But when I Add the JVM Argument in WAS its not coming up and native sterr logs shows - JMXetricAgent instrumented JVM, see same link what I have used Test wakeup

and then in around every 10 mints it keeps on writing Test wakeup but instance does not starts.

Also I have tried to run java command through command line like this --

[root@hostname var]# java -javaagent:/etc/ganglia/jmxmetric/jmxetric-master/jmxetric-1.0.6.jar=host=hostname,port=8649,mode=unicast,wireformat31x=true,config=/etc/ganglia/jmxmetric/jmxetric-master/jmxetric.xml,process=hostanem_m01 info.ganglia.jmxetric.JMXetricAgent

Getting same response JMXetricAgent instrumented JVM, Test wakeup

Can you all please suggest as what I am doing wrong here.

Thanks much in Advance (its been a week I am struggling with this)

"usual.java.main.class" is given just an example.. i believe you should remove it from JVM arguments.
