Outputting JMX Monitoring Points

If you need to programmatically access all JMX monitoring points for your Servlet app, do the following:

1. Add the following VM arguments to the Tomcat Run Configuration (This can be done in Eclipse/STS run configurations):

-Dcom.sun.management.jmxremote
-Dcom.sun.management.jmxremote.authenticate=false
-Dcom.sun.management.jmxremote.port=8234
-Dcom.sun.management.jmxremote.ssl=false

2. Then run the following Java Program:

package com.rim.platform.mdm.core.service.email;

import java.io.IOException;
import java.util.Set;

import javax.management.InstanceNotFoundException;
import javax.management.IntrospectionException;
import javax.management.MBeanAttributeInfo;
import javax.management.MBeanInfo;
import javax.management.MBeanServerConnection;
import javax.management.MalformedObjectNameException;
import javax.management.ObjectInstance;
import javax.management.ReflectionException;
import javax.management.remote.JMXConnector;
import javax.management.remote.JMXConnectorFactory;
import javax.management.remote.JMXServiceURL;

public class MonitoringPoints
{

    public MonitoringPoints()
    {
    }

    /**
     * @param args
     * @throws Exception
     */
    public static void main(String[] args) throws Exception
    {
        String host = "localhost"; 
        int port = 8234;
        String url = "service:jmx:rmi:///jndi/rmi://" + host + ":" + port + "/jmxrmi";
        printAll(url);
    }

    public static void printAll(String url) throws IOException, MalformedObjectNameException, 
            InstanceNotFoundException, IntrospectionException, ReflectionException
    {
        JMXServiceURL serviceUrl = new JMXServiceURL(url);
        JMXConnector jmxConnector = JMXConnectorFactory.connect(serviceUrl, null);
        try
        {
            MBeanServerConnection mbeanConn = jmxConnector.getMBeanServerConnection();
            // now query to get the beans or whatever
            Set beanSet = mbeanConn.queryMBeans(null, null);
            for (ObjectInstance instance : beanSet)
            {
                MBeanInfo info = mbeanConn.getMBeanInfo(instance.getObjectName());
                MBeanAttributeInfo[] mai = info.getAttributes();
                System.out.println("\n******* Monitoring points for: " + instance.getObjectName());
                for (MBeanAttributeInfo object : mai)
                {
                    System.out.println(object.getName());
                }
            }
        }
        finally
        {
            jmxConnector.close();
        }
    }
}
