Nirvana Enterprise Manager - Realm Drilldown

The realm drilldown view provides an overview of the characteristics as well as current status of a selected Nirvana realm, in a very similar way to the realm status view but focused in real time representation rather than historical representation.. In order to view the realm drilldown panel, you need to select a Realm node from the namespace, and click on the drilldown tab.

This section will describe the type of status information that you can observe from the Realm Drilldown view.

The top of the screen displays a panel containing the following values :

  • Name - The name of the selected realm
  • Threads - Number of threads within the Realm Server's JVM
  • Realm Up Time - How long the realm has been running for
  • Last Update - The time that the last status update was sent by the realm

The top of the Drilldown panel contains 2 large real time pie charts illustrating a break down of total events published and consumed across the Nirvana Realm, as well as a breakdown of the JVM used and free memory.

The bottom of the screen displays 4 panels named Event Status, Totals, Connection Status and Memory Usage respectively. These panels and the information displayed are described below.
