本文介绍如何通过JMX监控ActiveMQ的消息队列。首先需要在ActiveMQ配置文件中开启JMX支持，并指定管理上下文及端口。然后可通过JConsole工具连接到本地JMX服务，或使用JMX API进行编程式监控。文章提供了具体的配置示例和Java代码示例，展示如何获取Broker、Queue和Topic的状态信息。

一、通过JMX控制台监控

在activemq的配置文件中增加JMX配置

配置文件位置：${ActiveMQ.Base}/conf/activemq.xml

将broker节点添加属性useJmx

<broker useJmx="true" brokerName="BROKER1">

...

</broker>

运行jconsole.exe，位置为${JAVA_HOME}/bin/jconsole.exe

url填写：

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

二、JMXAPI开发

配置文件位置：${ActiveMQ.Base}/conf/activemq.xml

将broker节点添加属性useJmx，添加managementContext节点，配置连接端口

 <broker xmlns="http://activemq.apache.org/schema/core" brokerName="localhost" dataDirectory="${activemq.data}" useJmx="true">

      <managementContext>

         <managementContext connectorPort="2011" jmxDomainName="my-broker"/>

      </managementContext>

</broker>

通过URL：service:jmx:rmi:///jndi/rmi://localhost:2011/jmxrmi初始化JMXConnector

通过NAME：my-broker:BrokerName=localhost,Type=Broker获取BrokerViewMBean，可以获取Broker的相关属性，可以通过BrokerViewMBean获取QueueViewMBean及TopicViewMBean等，从而得到Queue及Topic的属性。

具体实现参考JMX API

public static void main(String[] args) throws Exception {
		JMXServiceURL url = new JMXServiceURL(
				"service:jmx:rmi:///jndi/rmi://localhost:2011/jmxrmi");
		JMXConnector connector = JMXConnectorFactory.connect(url, null);
		connector.connect();
		MBeanServerConnection connection = connector.getMBeanServerConnection();
		ObjectName name = new ObjectName(
				"my-broker:BrokerName=localhost,Type=Broker");
		BrokerViewMBean mbean = (BrokerViewMBean) MBeanServerInvocationHandler
				.newProxyInstance(connection, name, BrokerViewMBean.class, true);
		log("**************");
		log("getBrokerId:" + mbean.getBrokerId());
		log("getBrokerName:" + mbean.getBrokerName());
		log("getTotalMessageCount:" + mbean.getTotalMessageCount());
		log("getTotalEnqueueCount:" + mbean.getTotalEnqueueCount());
		log("getTotalDequeueCount:" + mbean.getTotalDequeueCount());
		log("**************");
		log("==============");
		ObjectName[] queueNames = mbean.getQueues();
		log("getQueues count:" + queueNames.length);
		for (ObjectName queueName : queueNames) {
			
			QueueViewMBean queueMbean = (QueueViewMBean) MBeanServerInvocationHandler
					.newProxyInstance(connection, queueName,
							QueueViewMBean.class, true);
			log("------------");
			log("queueName:" + queueMbean.getName());
			log("queuesize:" + queueMbean.getQueueSize());
			log("getEnqueueCount:" + queueMbean.getEnqueueCount());
			log("getDequeueCount:" + queueMbean.getDequeueCount());
		}
		log("==============");
		log("++++++++++++++");
		ObjectName[] topicNames = mbean.getTopics();
		log("topic count:" + topicNames.length);
		for (ObjectName topicName : topicNames) {
			TopicViewMBean topicMBean = (TopicViewMBean) MBeanServerInvocationHandler
					.newProxyInstance(connection, topicName,
							TopicViewMBean.class, true);
			log("------------");
			log("topivName:"+topicMBean.getName());
			log("topivSize:"+topicMBean.getQueueSize());
			log("getEnqueueCount:"+topicMBean.getEnqueueCount());
			log("getDequeueCount:"+topicMBean.getDequeueCount());
		}
		log("++++++++++++++");
