You have the ability in SQL Diagnostic Manager to snooze or pause all alert generation for a specified period of time. For example, you can snooze a specific alert through the Active Alerts tab. Right-click the alert that you no longer want to view, and then select Snooze Alert.
If you want to pause multiple alerts at the same time, you can mass snooze alert generation. To mass snooze, right-click a specific instance, and then select Snooze Alerts. This option is also accessible when right-clicking a specific tag, using certain server views, and when using the Tools menu.
This feature is important if you are working on known issues and you want to avoid unnecessary alert traffic.
The Resume Alerts option allows you to resume any alerts set to snooze.
