1. Create a notification profile that you want to be applied to your systems.
2. Set the "Downtime Notification Delay" to "Notify after two continuous failures"
We do this for the default notification profile and have found it to significantly improve the quality of life for our admins. This means that you do not get alerts for restarting services, but still get alerted if the service fails to restart, which is awesome.
We also have a "Critical Devices" profile, which notifies immediately.
