![]() ![]() Each MBean is registered with a unique name within the MBean server. MBean Server or JMX AgentĪn MBean Server is a repository of MBeans. ![]() The platform MBeans introduced below are all MXBeans. In this way, you can be sure that your MBean will be usable by any client, including remote clients, without any requirement that the client have access to model-specific classes representing the types of your MBeans. * provides a simple way to code an MBean that only references a predefined set of types. you don’t want your interface name to end with MXBean, you can simply apply the annotation to your interface definition. This is to say your manageable class may be called Car and your MXBean interface may be named CarMXBean.Īlternatively, if you don’t want to follow the naming convention for MXBeans, i.e. The name of this interface must end with MXBean (as opposed to MBean with standard MBeans), however the prefix does not have to match the name of the manageable class. Fortunately, other types of MBeans allow you to manage objects without modifying classes. While this is okay in some projects, in others (especially when there are many classes involved) this is not acceptable. Standard MBeans are easy to write, but they require that your classes be modified. Register your MBean with the MBean server.The agent class must contain an MBean server. Modify your Java class so that it implements the interface you’ve created.For example, if the Java class whose objects you want to manage is called Car, the interface must be called CarMBean. Create an interface named after your Java class plus the suffix MBean.Here are what you need to do to manage a Java object using a standard MBean. Each MXBean encapsulates a part of VM functionality such as the class loading system, just-in-time (JIT) compilation system, garbage collector, and so on. Platform MBean - is an MBean for monitoring and managing the Java VM and other components of the Java Runtime Environment (JRE).Typed notifications that can be emitted by the MBean.Named and typed operations that can be invoked.Named and typed attributes that can be read and written.An MBean has a management interface consisting of the following. MBeans are Java objects that represent resources to be managed.MBean Server - container where MBeans are registered using a unique name.This object interacts with your app to get/set attributes or invoke methods. MBean or Managed Bean - Implementation of the MBean interface.MBean Interface - Interface to which management app connects to. ![]() Managed Resource - your application to be instrumented.JMX API - The package provides the interface for monitoring and managing the VM.Technology that enables to monitor and manage applications running in a JVM locally or remotely. Sun’s reference implementation - lib/jmxri.jar (JMX reference implementation Java class package) and lib/jmxtools.jar (JMX toolkit). ![]()
