ActiveMQ JMX使用

一、说明

　　ActiveMQ使用过程中，可以使用自带的控制台进行相关的操作以及查看，但是当队列数相当多的时候，在查询以及整体的监控上，就可能相当的不便。所以可通过JMX的方式，进行MQ中队列相关指标的以及整体健康性能等收集展示。

二、JMX功能开启

　　2.1、broker标签中添加  userJmx="true":

　　

　　2.2、配置 managementContext

　　

　　其中 用户名、密码及权限配置在 jmx.password 和 jmx.access 文件中。

三、Java应用连接使用

　　3.1、获取在线的队列消费者IP

private static final String queueObjectName = "org.apache.activemq:type=Broker,brokerName=localhost,destinationType=Queue,destinationName=%s";
	private static final String brokerAddress = "service:jmx:rmi:///jndi/rmi://%s/jmxrmi";

private static List<String> getQueueConsumers(String user, String password, String ip, String queueName) throws Exception{
		List<String> result = Lists.newArrayList();
		String url = String.format(brokerAddress, ip);
		Map<String, Object> credentials = new HashMap<>();
	    credentials.put(JMXConnector.CREDENTIALS, new String[] {user, password});
	    
        JMXServiceURL urls = new JMXServiceURL(url);
        
        JMXConnector connector = JMXConnectorFactory.connect(urls,credentials);
        connector.connect();
        MBeanServerConnection conn = connector.getMBeanServerConnection();
        
        ObjectName name = new ObjectName(String.format(queueObjectName, queueName));
        QueueViewMBean queueViewMBean = MBeanServerInvocationHandler.newProxyInstance(conn, name, QueueViewMBean.class, true);
        for (ObjectName mbeanNameConsumerObjectName : queueViewMBean.getSubscriptions()) {
        	SubscriptionViewMBean subscriptionViewMBean = MBeanServerInvocationHandler.newProxyInstance(conn, mbeanNameConsumerObjectName,SubscriptionViewMBean.class, true);
        	ObjectName connectionObjectName = new ObjectName(subscriptionViewMBean.getConnection().getCanonicalName());
        	ConnectionViewMBean connectionViewMBean = MBeanServerInvocationHandler.newProxyInstance(conn, connectionObjectName,ConnectionViewMBean.class, true);
        	if (connectionViewMBean != null) {
        		result.add(connectionViewMBean.getRemoteAddress().replace("//", "").split("\\:")[1]);
//        		System.out.println(connectionViewMBean.getRemoteAddress()+"|"+connectionViewMBean.getClientId());
            }
        }
        return result;
	}

　　其中方法的参数： ip - broker的 ip 地址，user - JMX登录访问的用户名，password - JMX登录访问的密码，queueName - 待查询的队列名

 　　3.2、获取队列的出队、入队以及积压数等指标信息　

package workMQ;

import com.google.common.collect.Maps;

public class Test08 {

	public static void main(String[] args) throws Exception {
		
		String ip = "192.168.25.43:9607";
		
		String url = String.format("service:jmx:rmi:///jndi/rmi://%s/jmxrmi",ip);
		Map<String, Object> credentials = new HashMap<>();
	    credentials.put(JMXConnector.CREDENTIALS, new String[] {"admin", "activemq"});
	    
        JMXServiceURL urls = new JMXServiceURL(url);
        
        JMXConnector connector = JMXConnectorFactory.connect(urls,credentials);
        connector.connect();
        MBeanServerConnection conn = connector.getMBeanServerConnection();
        
        ObjectName name = new ObjectName("org.apache.activemq:brokerName=localhost,type=Broker");
        BrokerViewMBean mBean = (BrokerViewMBean)MBeanServerInvocationHandler.newProxyInstance(conn, name, BrokerViewMBean.class, true);
        
        for(ObjectName na : mBean.getQueues()){
            QueueViewMBean queueBean = (QueueViewMBean) MBeanServerInvocationHandler.newProxyInstance(conn, na, QueueViewMBean.class, true);
        	System.out.println("队列的名称："+queueBean.getName());
        	System.out.println("消息积压数："+queueBean.getQueueSize());
        	System.out.println("入队："+queueBean.getEnqueueCount());
        	System.out.println("出队："+queueBean.getDequeueCount());
        	System.out.println("消费者数："+queueBean.getConsumerCount());
        	System.out.println("生产者数："+queueBean.getProducerCount());
        	//还有很多队列指标信息，具体可根据实际使用获取
        　　}
	}
}

 

四、JDK自带JConsole连接

　　1、JDK安装目录下的 bin 文件夹，点击JConsole.exe

　　2、选择远程进程，输入 brokerAddress、username、password

　　brokerAddress 格式 ： service:jmx:rmi:///jndi/rmi://具体的brokerip地址:配置的JMX的port访问端口/jmxrmi

　　username、password 即是JMX的访问用户名、密码

　　

　　3、进入后，可查看相关信息
