Snoozing is a way to temporarily stops notifications of an active alert for a certain amount of time. You can snooze an alert on the Alerts detail page.
When an alert is snoozed, the alert's status becomes suppressed. All notifications related to that alerts are stopped from that moment until the end of the specified time. When the snooze ends, the alert's status becomes active again. ModelOps allows you to unsnooze an alert explicitly and make it active before the snooze time ends.
