In one of my earlier posts I had covered about "VisualGC" which was a performance monitoring tool with SunJDK.
VisualGC: Performance Monitoring tool for Oracle SOA Suite
In this post I would like to cover a similar powerful tool called "JRockit Mission Control" which gets shipped along with JRockit JVM and can be used for performance monitoring and JVM profiling.
For enabling this tool, you first have to modify the setDomainEnv.sh file and add the java properties as mentioned below.
EXTRA_JAVA_PROPERTIES="${EXTRA_JAVA_PROPERTIES} -Xmanagement:ssl=false,authenticate=false,autodiscovery=true"
export EXTRA_JAVA_PROPERTIES
This enables the client machine to connect to the WLS server and pull the JVM stats. I have not specified the port argument above. By default it is 7091, incase a different port is to be used the same can be appended to the comma separated argument list above.
Now you can go to the Jrockit installation folder on your windows/linux machine and navigate to the bin folder where you can find the jrmc file. Run the same and after starting JRMC the following screen appears
Create a new connection to your Weblogic Server
I will be covering deep dive details about JRMC in a later post. For now lets enjoy the cockpit styled UI :)

Next you can start monitoring the JVM/CPU usage and drill down into other JVM options in real time.
