Resolve Alerts

Atlas issues alerts for the database and server conditions configured in your alert settings. When a condition triggers an alert, Atlas displays a warning symbol on the cluster and sends alert notifications. Your alert settings determine the notification methods. Atlas continues sending notifications at regular intervals until the condition resolves or you delete or disable the alert.

View Alerts

To view all open alerts, click Alerts in the Project section of the left navigation.

Acknowledge Alerts

To acknowledge an alert, click Alerts in the Project section of the left navigation, locate the alert, and click Acknowledge.

If an alert uses PagerDuty for alert notifications, you can acknowledge the alert only on your PagerDuty dashboard.

When you acknowledge an alert, Atlas sends no further notifications until either the acknowledgement period ends, you resolve the alert condition, or you unacknowledge alert. If an alert condition ends during an acknowledgment period, Atlas sends a notification.

Increase Cluster Capacity

To resolve an alert by increasing your cluster’s capacity, see Modify a Cluster.
