View cluster details

Learn more about viewing the details of any particular cluster.

The Clusters tab of the Broker VMs page (Settings → Configurations → Data Broker → Broker VMs) enables you to view detailed information regarding your High Availability (HA) cluster.

The Clusters table enables you to monitor and mange your cluster nodes and applets, and view stats.

In addition, when each cluster is expanded, a table is displayed, which enables you to view detailed information regarding the various Broker VM nodes that are currently added to your cluster. If you haven't added any Broker VM nodes to a particular cluster, the table is empty.

Clusters Table

The following table describes all the fields that are available in the Clusters table. You can hide any field column using the column manager.

Fields	Description
CLUSTER NAME	Beside the full name of each cluster, a status indicator is displayed with one of the following colors: Green: Healthy, the Primary node and all available standby nodes are connected and operating with no warnings, and all activated applets are running without a problem. Orange: Warning as the system has detected errors in the cluster, but the applets can still be running. For example, all applets are running normally in the Primary Broker VM, but no available standby nodes are detected, or the Primary node is operating fine, but there is an applet that failed to start in one of the standby nodes. The errors must be addressed as soon as possible. Red: Critical as the system has detected one or more critical errors in the cluster, and nodes are not able to run some applets. For example, an error was detected in some Primary applet and no standby node is available for failover. All errors must be addressed as soon as possible. Black: Unavailable as the cluster doesn’t have any peer nodes configured.
STATUS	Connection status of the cluster according to the statuses and colors explained in the CLUSTER NAME field above. Unavailable clusters do not display CPU USAGE, MEMORY USAGE, and DISK USAGE information. Notifications about the cluster losing connection between applets and Broker VM nodes appear in the Notification Center.
CPU USAGE	Average CPU utilization between all nodes in the cluster as a percentage.
MEMORY USAGE	Sum of all memory in use out of the sum of the total memory on all nodes in the cluster as a percentage.
DISK USAGE	Sum of all disk space in use out of the sum of the total disk space on all nodes in the cluster as a percentage.
APPS	List of active applets and the connectivity status for each. Colors depict the following statuses: Green (Connected): Indicates the applet has no issues. Orange (Warning): Indicates the applet has minor issues. Red (Error): Indicates the applet has errors. White (Inactive): Indicates the applet is inactive. Note For more information on troubleshooting errors and warnings for these applets, see Troubleshoot Broker VM applet errors.

Cluster Broker VM Nodes Table

The fields that are available in the Broker VM nodes table for each cluster are similar to many of the fields that are displayed in the table for the Broker VMs in the Brokers tab. For more information on these fields, see Manage Broker VM.
