JMX - Java Management Extensions, Java Management Extensions, is a framework for the application, device, system, etc. JMX can span a series of heterogeneous operating system platforms, system architecture, and network transport protocols, flexible development seamless integration systems, networks, and service management applications. The JMX architecture is divided into the following four levels: 1) Instrumentation Level: The information model is mainly defined. In JMX, various management objects exist in the form of management components, and register to the MBean server when you need to manage. This layer also defines the notification mechanism and some auxiliary metadata classes. 2) Agent Level: It mainly defines various services and communication models. The core of this layer is an MBean server, and all management components need to be registered with it to manage. Registering the management component on the MBean server is not directly communicating with the remote application, and they communicate through the protocol adapter and connectors. The protocol adapter and connectors are also registered with the MBean server in the form of a management component to provide the corresponding services. 3) Distributed Service Level: Mainly defined management interfaces and components that can operate on the agent layer so managers can operate the agent. However, the current JMX specification does not give specific specifications for this layer. 4) Additional Management Protocol API: The defined API is mainly used to support currently existing network management protocols, such as SNMP, TMN, CIM / WBEM, etc.
