You can configure SAP Control Center to notify you when a resource requires attention.
You do this by setting up a predefined alert that is triggered when a performance counter enters a particular state or passes a threshold value that you set. When the alert goes off, it generates an alert notification.
An alert notification takes the form of a visual indicator in the Alert Monitor and, optionally, an e-mail message. The Alert Monitor displays information about the alert, including the resource name, alert severity, value, and date. You can resolve the alert or allow it to escalate.
