The UserSpecified monitors MBean allows the (administrative) user to create their own instances of the various built-in Java subclasses of javax.management.monitors.Monitor which are then managed and persisted through the UserSpecified monitors MBean.

The creation of the Monitor instances is done via operations on the UserSpecified monitors MBean whereas further configuration of the Monitor instances is done via attributes and operations on the Monitor instances themselves (which are also MBeans). The UserSpecified monitors MBean is instantiated out-of-the-box in all server JVMs.
