This guide will help you setup a remote jvm monitoring tool using jconsole.

The setup:
1.) Ubuntu 12.04
2.) Glassfish 3.1.2.2
3.) jdk1.6.0_32

Steps:
1.) In your glassfish's default domain1 domain.xml file, /glassfish_home/glassfish/domains/domain1/config/domain.xml, add the following lines in the jvm section:
<jvm-options>-Djava.net.preferIPv4Stack=true</jvm-options>
<jvm-options>-Dcom.sun.aas.jconsole.server.cbport=18687</jvm-options>
<jvm-options>-Dcom.sun.management.jmxremote.ssl=false</jvm-options>
<jvm-options>-Dcom.sun.management.jmxremote.authenticate=false</jvm-options>
<jmx-connector address="0.0.0.0" auth-realm-name="admin-realm" name="system" port="18686" protocol="rmi_jrmp" security-enabled="false"/>

//you can set the fully qualified domain name if you have, otherwise we will connect using ip
<jvm-options>-Djava.rmi.server.hostname=mydomain.com
2.) Rename /usr/lib/jvm/jdk1.6.0_32/jre/lib/management/jmxremote.password.template->/usr/lib/jvm/jdk1.6.0_32/jre/lib/management/jmxremote.password

3.) Uncomment monitorRole and controlRole users

4.) Change the owner of /usr/lib/jvm/jdk1.6.0_32/jre/lib/management/jmxremote.password, the same as the owner of glassfish folder:
sudo chown owner:group /usr/lib/jvm/jdk1.6.0_32/jre/lib/management/jmxremote.password
sudo chmod 600 /usr/lib/jvm/jdk1.6.0_32/jre/lib/management/jmxremote.password

5.) Restart glassfish and connect from a remote machine using JConsole, enter the IP and port 8686. Example: 192.168.0.106:8686
