System event notifications
You can configure system event notifications on the Farm > Site > Settings > Notifications tab. Notifications are used to alert the administrator about system events via email. When you configure notifications, the settings apply to all servers in the Farm.
To configure notifications, you first need to configure notification handlers where you can specify threshold values (where available) and whether an administrator should be notified via email. You can also configure notification scripts, which will be automatically executed when an event occurs.
