Viewing Information for a Cluster
You can view information for an individual cluster by expanding the Clusters node in the navigation pane and selecting the node for the required cluster. The view provides an overview of the characteristics as well as current status of a selected cluster.
View of a Cluster
The top of the view shows the realms that have been defined for the cluster.
The view includes a real time graph illustrating the total number of events published (yellow) and consumed (red) across all realms in the cluster.
The bottom of the screen displays 3 panels named Totals, Event Status and Connection Status. These panels and the information displayed are described below.

The Totals section describes the following :
Realms- The number of realms within the cluster

The Event Status section describes the following :

Consumed - The total number of events consumed from all channels, queues and services across all realms within the cluster
Published/Sec - The number of events published to all channels, queues and services, per second across all realms within the cluster
Consumed/Sec - The number of events consumed from all channels, queues and services, per second across all realms within the cluster
