Java Mission Control uses Managed Beans (MBeans) to provide a unified and consistent interface for monitoring and managing Java application performance. MBeans are managed objects that follow the design patterns that conform to the JMX specification. An MBean can represent a device, an application, or any resource that needs to be managed. The management interface of an MBean comprises a set of attributes, operations, and notifications.
The MBean Browser provides access to all registered MBeans. MBeans are registered in the Management Server, which can be accessed by clients compliant with the Java Management Extensions (JMX), for example, the JMX Console in Java Mission Control.
The MBean Browser tab is divided into the following panels:
MBean Tree: A list of all registered MBeans (listed by domain). You can filter the list by MBean name using the Filter field. To toggle automatic updates, use the button in the top right corner of the MBean Tree panel.
MBean Features: A panel with the following subtabs:
Attributes: Lists the attributes for the selected MBean.
Operations: Lists the operations you can invoke from the selected MBean.
Notifications: Lists the notifications prompted by the MBean during runtime.
Metadata: Contains information that describes the MBean.
