Viewing a Realm
The Realm view provides information about the current status of the set of Universal Messaging realms that the Enterprise Manager is monitoring. When you select a realm node from the namespace, the status panel is displayed by default for the realm.
The top of the screen displays a panel containing the following information:
Name - The name of the selected realm.
Threads - The number of threads in the realm server's JVM.
Realm Up Time - How long the realm has been running.
Last Update - The time that the last status update was sent by the realm.
Publish state - Whether server publishing is paused.
The Status panel contains real-time graphs illustrating the total number of events published (yellow) and consumed (red) across the Universal Messaging realm, as well as the direct memory usage history and heap memory usage history for the selected realm.
The bottom of the screen displays four panels named Event Status, Totals, Connection Status, and Memory Usage. These panels and the information displayed are described below.
