The MBean Explorer displays the MBean features (both attributes and operations) in its hierarchy. Double-clicking on a feature will open a MBean Editor, display the page corresponding to the feature type and select the feature.
Since it's possible to have many MBean Editors opened at the same time, the MBean Explorer
has the Link With Editor button
to synchronize selections between the active MBean Editor and
the MBean Explorer (and vice versa).
The MBean Explorer has also a filter text that can be used to filter among all the MBeans the few ones, which interest you.
For example, if you are only interested by MBeans related to memory, typing memo will show any node (domain, mbean, attribute, or operation) that matches that text, as well as that node's parents and children. So if an MBean matches, all attributes and operations from that bean will show. If, however, an attribute or operation name (a leaf node) matches, only that node and its parents in the tree will show.
The
Collapse All button
on the MBean Explorer toolbar is used to collapse all the MBeans and
display only the domains. It is also possible to double click on a node to expand/collapse it.
The MBean Editor is composed of several pages:
the Attributes page
the Operations page
the Notifications page
the Info page
The Attributes and Operations pages display a list for either the MBean attributes or operations as well as details for the selection.
It is possible to toggle the layout between the list and the details either vertically
(by default) or horizontally with the help of the special icons
in the right top corner of the editor.
One more page in the MBean Editor is the Notifications page, which gives the possibility to subscribe (resp. unsubscribe) to a MBean to receive its notifications by checking (resp. unchecking) the Subscribe button in the right top corner.
The list of notifications is refreshed every time a new notification is received:
It is only possible to subscribe to MBean, which emits notifications (they must be NotificationBroadcaster).
