activeMQ监控

1. JMX连接器-rmi

1.1 定义

• JMX API定义了一个标准连接器 - RMI Connector,它支持通过RMI远程访问一个MBeanServer

1.2 RMI连接器服务器

• 地址示例如下：

  service:jmx:rmi://localhost:1099/jndi/rmi://localhost:8899/myname

• 在这个JMXServiceURL中：

  1. 第一个rmi指的是rmi连接器，表示用连接器使用RMI传输协议，第二个rmi指定RMI注册RMI连服务接器存储存根
  2. localhost:1099: 这个是connector server的IP和端口，该部分是一个可选项，可以被省略掉。如果省略的话，则connector server会随机任意选择一个可用的端口
  3. /jndi/rmi://localhost:8899/myname: 这个是connector server的路径，表示Connector server的stud是使用JNDI API绑定在rmi://localhost:8899/myname这个地址上

1.3 创建一个RMI connector server

• 通常是提供一个RMI connector server的连接器地址，用JMXConnectorServerFactory.newJMXConnectorServer方法来创建RMI connector cerver
• 参考 : JMX API
