Java Runtime Monitor

Java Runtime Monitor provides out-of-the-box remote monitoring and management on the Java platform and of applications that run on it.

PreRequisite: To monitor a JDK1.5 JVM and above, the following java runtime options needs to be added to your application

-Dcom.sun.management.jmxremote -Dcom.sun.management.jmxremote.port=1099 -Dcom.sun.management.jmxremote.ssl=false -Dcom.sun.management.jmxremote.authenticate=false

Note : Port number "1099" can be replaced with the actual port number of the JMX agent.
Also Note: Support is available for JRE1.5 and above

Example: To enable Java Runtime Monitor in JBoss do the following

Edit the run.sh/bat under JBoss home/bin. Append the following command to JAVA_OPTS

JAVA_OPTS =-Dcom.sun.management.jmxremote -Dcom.sun.management.jmxremote.port=1099 -Dcom.sun.management.jmxremote.ssl=false -Dcom.sun.management.jmxremote.authenticate=false %JAVA_OPTS%

To enable Java Runtime Monitor in Tomcat do the following

Edit the run.sh/bat under Tomcat home/bin. Append the following command to JAVA_OPTS

JAVA_OPTS =-Dcom.sun.management.jmxremote -Dcom.sun.management.jmxremote.port=1099 -Dcom.sun.management.jmxremote.ssl=false -Dcom.sun.management.jmxremote.authenticate=false %JAVA_OPTS%

Follow the steps given below to create a Java Runtime Monitor:

• Click New Monitor. Choose Java Runtime.

  
  

• Enter the IP Address or hostname of the host in which the Monitor is running.

  
  

• Enter the SubNetMask of the network.

  
  

• Provide the port number in which JDK is running (default: 1099). Also, you can provide multiple ports separated by commas.

  
  

• Enter the polling interval time in minutes.

  
  

• Enter the JNDI name. For example, /jmxrmi.

  
  

• If Authentication is enabled, enter the Username and password.

  
  

• Choose the Monitor Group, to which you want to associate the Monitor (optional).

  
  

• Click Add Monitor(s). This discovers the Monitors from the network and starts monitoring them.
