JMX activemq (1)

We know that the management interface of activemq broker is provided through JMX.

A simple access method is to enter

service:jmx:rmi:///jndi/rmi://localhost:1099/jmxrmi

Note that:

1. The default JMX function is not enabled. You need to add usejmx = "true" to the broker configuration of activemq. xml"

2. In managementcontext, change it to createconnector = "true". (You can also modify the JMX port and domain here)

(See http://activemq.apache.org/jmx.html)

It is not easy to operate through jconsole. In particular, we need to integrate the management of brokers and queue into our management system.

At this time, we need to use the JMX programming interface to interact with the broker.

You can first write a small program to see what is provided in the broker's JMX.

package kk;import java.util.Iterator;import java.util.Set;import javax.management.MBeanAttributeInfo;import javax.management.MBeanInfo;import javax.management.MBeanOperationInfo;import javax.management.MBeanServerConnection;import javax.management.ObjectInstance;import javax.management.ObjectName;import javax.management.remote.JMXConnector;import javax.management.remote.JMXConnectorFactory;import javax.management.remote.JMXServiceURL;public class TestJMX {public static void main(String[] args) throws Exception {String surl = "service:jmx:rmi:///jndi/rmi://localhost:1099/jmxrmi";JMXServiceURL url = new JMXServiceURL(surl);JMXConnector jmxc = JMXConnectorFactory.connect(url, null);MBeanServerConnection mbsc = jmxc.getMBeanServerConnection();System.out.println("Domains:---------------");String domains[] = mbsc.getDomains();for (int i = 0; i < domains.length; i++) {System.out.println("\tDomain[" + i + "] = " + domains[i]);}System.out.println("all ObjectName：---------------");Set<ObjectInstance> set = mbsc.queryMBeans(null, null);for (Iterator<ObjectInstance> it = set.iterator(); it.hasNext();) {ObjectInstance oi = (ObjectInstance) it.next();System.out.println("\t" + oi.getObjectName());}System.out.println("org.apache.activemq:BrokerName=localhost,Type=Broker：---------------");ObjectName mbeanName = new ObjectName("org.apache.activemq:BrokerName=localhost,Type=Broker");MBeanInfo info = mbsc.getMBeanInfo(mbeanName);System.out.println("Class: " + info.getClassName());if (info.getAttributes().length > 0){for(MBeanAttributeInfo m : info.getAttributes())System.out.println("\t ==> Attriber：" + m.getName());}if (info.getOperations().length > 0){for(MBeanOperationInfo m : info.getOperations())System.out.println("\t ==> Operation：" + m.getName());}jmxc.close();}}

Output result:

The broker attributes and operations are obtained above, and the attributes and operation lists of other objects can also be obtained.
Based on this, we can get the object objects such as broker, connector, producer, consumer, queue, topic, and subctor, and further operate on them.

To be continued.
