To prevent an excessive number of email notifications from being sent when alerts are triggered, StorageGRID attempts to group multiple alerts in the same notification.
Refer to the following table for examples of how StorageGRID groups multiple alerts in email notifications.
Behavior | Example |
---|---|
Each alert notification applies only to alerts that have the same name. If two alerts with different names are triggered at the same time, two email notifications are sent. |
|
For a specific alert on a specific node, if the thresholds are reached for more than one severity, a notification is sent only for the most severe alert. |
|
The first time an alert is triggered, StorageGRID waits 2 minutes before sending a notification. If other alerts with the same name are triggered during that time, StorageGRID groups all of the alerts in the initial notification. |
|
If an another alert with the same name is triggered, StorageGRID waits 10 minutes before sending a new notification. The new notification reports all active alerts (current alerts that have not been silenced), even if they were reported previously. |
|
If there are multiple current alerts with the same name and one of those alerts is resolved, a new notification is not sent if the alert reoccurs on the node for which the alert was resolved. |
|
StorageGRID continues to send email notifications once every 7 days until all instances of the alert are resolved or the alert rule is silenced. |
