When the cascading service MBean is instantiated, you can pass it an object name pattern. This object name pattern is applied to the list of MBeans in the subagent's source MBean server to determine those MBeans that are to be cascaded into the master agent's target MBean server. The filtering is activated for the life of the of the mount operation, namely, until unmount is called for that mount point. Care must be taken when using the ObjectName pattern, so as not to implement cascading hierarchies that are not analogous to File System mount operations.
The object name pattern is used to filter any new MBean that is registered in the source MBean server. If the new MBean meets the filter criteria, it will become visible and be cascaded into the target MBean server.
