Notification policies are a series of Alert Center notifications that trigger when a threshold falls "out" of (exceeds or falls below) its configured criteria.
Note: A notification policy must be applied to a threshold in order for it to send notifications that threshold. You apply a notification policy to a threshold from a threshold's configuration dialog. For more information, see Configuring Alert Center thresholds.
Notification policies are managed from the Alert Center Notification Policies dialog.
Caution: When you delete a policy from the list, it is removed from any threshold to which it is assigned.
