jmx jstatd remote debug configuration in JVM

To start the jstatd daemon, follow these steps:

Note : Close all the java based applications before starting jstatd.

Create a permissions policy (for example, jstatd.all.policy) that contains the following contents:

grant codebase "file:${java.home}/../lib/tools.jar" { permission java.security.AllPermission; };

Start the jstatd daemon, and specify the policy file and the port that you want to use. The daemon is found in the Java Development Kit (JDK) bin directory. Note: The location for that directory depends on the operating environment.
For UNIX operating environments, specify the following:

JAVA_HOME/bin/jstatd -p 1199 -J-Djava.security.policy=jstatd.all.

For Windows operating environments, specify the following:

JAVA_HOME\bin\jstatd -p 1199 -J-Djava.security.policy=jstatd.all.policy

Remote Monitoring via JMX

To monitor a Java virtual machine (JVM) via JMX, follow these steps:

Add the following arguments to the target JVM:

-Dcom.sun.management.jmxremote.authenticate=false -Dcom.sun.management.jmxremote.ssl=false -Dcom.sun.management.jmxremote.port=4090

Restart the JVM so that the new arguments take effect.
Verify that the JMX port (4090 in this example) is open and listening. Once you verify that the port is open and listening, you can connect to the port for remote monitoring.
