MBean Server

The MBean server, referred to as the framework in Java Dynamic Management Kit 3.x versions versions, is a registry for JMX manageable resources which are exposed to management operations in an agent. It provides a management framework with services for manipulating JMX manageable resources that is protocol-independent and information model-independent. All management operations performed on these resources are done through the MBean server management interface. You can create and manage objects by registering them within the MBean server, thus, making them visible to management applications. The MBean server includes a library of reusable core agent services in the form of manageable objects, as specified by Java Management extensions (JMX). These services include mlet, timer, monitoring and filtering.

You can register objects in the MBean server through:

• The agent application itself.

• A remote management application (through a connector or a protocol adaptor).

Any JMX manageable resource that you want to access for management operations must be registered in the MBean server. This MBean needs to be assigned a unique object name. The manager and the agent then use this object name to identify the object on which it is to perform a management operation. If you do not specify the object name explicitly, the MBean implementation may itself provide a name by default. It is possible to have multiple MBean servers within the same Java Virtual Machine (JVM)..
