# The WebLogic Server® MBean Reference

A managed bean (MBean) is a Java bean that provides a Java Management Extensions (JMX) interface. JMX is the J2EE solution for monitoring and managing resources on a network. Like SNMP and other management standards, JMX is a public specification and many vendors of commonly used monitoring products support it.

BEA WebLogic Server provides a set of MBeans that you can use to configure, monitor, and manage WebLogic Server resources through JMX. This reference document organizes WebLogic Server MBeans into the following categories:

- MBeanServer Services, which serve as your entry point into navigating the MBean hierarchies. Some of these MBeans contain attributes and operations for managing changes to WebLogic Server configuration MBeans.
- Configuration MBeans, which expose attributes and operations for configuring WebLogic Server resources.
- Runtime MBeans, which provide information about the runtime state of its resources.
- New MBeans, which have been added in the current release of WebLogic Server. These new MBeans are also listed in other categories in this document (for example, new runtime MBeans are also listed under the Runtime MBeans category).
- Deprecated MBeans, which are deprecated in the current release of WebLogic Server.
