Service Status Preview Area

The list of installed service components in the cluster is displayed on the left of the home page. You can view the status and alarms of each service.

The icon on the left of each service name indicates that the service is running properly; the icon indicates that the current service fails to start; and the icon indicates that the current service is not started.

You can also check whether alarms have been generated for the service on the right of the service name. If alarms have been generated, the alarm severities and the number of alarms are displayed.

The icon displayed on the right of the service name indicates that the service configuration has expired.

Monitoring Status Report Area

The chart area is on the right of the homepage, which displays key monitoring metric reports, such as the status of all hosts in the cluster, host CPU usage, and host memory usage. You can customize monitoring reports to display in this area. For details about how to manage monitoring metrics, see Managing Monitoring Metric Reports.
