Alerting

On the Alerting screen, you can configure alerts for user-defined conditions that could indicate problems in the cluster. You can use one of the available numeric metrics to specify the condition. For example, you can specify a condition of prolonged, high CPU load or a condition of high amount of disk usage on nodes. When the condition is observed for the time duration that you specified, Control Center sends an email and/or SMS notification.

Alert notifications are sent through notification channels. A notification channel is either SMS-based or email-based. You can assign multiple channels to each alert.

Creating Alerts

On the CONFIGURATIONS tab, click the ADD ALERT button and fill out the fields of the dialog box that appears.

An alert is in one of three states:

  • OK. The alert condition is not violated.

  • Pending. The alert condition has been violated, but the grace period hasn’t expired yet.

The EVENTS tab maintains records that report the history of alert state changes.
