Use the Alerts and Notifications tab to monitor alerts and notifications, and to create alert and notification definitions.
Alert Definition: An alert definition is a specification of conditions that are necessary to trigger an alert. An alert is a specific instance in time when a device meets the conditions specified in the alert definition. Alert definitions consist of a device template, device metric, condition expression, and the number of times the condition must be true for a device to trigger that alert. For example, you can define an alert to trigger whenever the temperature of a device exceeds 130 degrees. You can set a pre-defined notification definition in your alert definition to notify the users through email or a user-defined callback API whenever the alert is triggered.
Notification Definition: Notification definitions define where the notification must be sent, who the sender is, and the number of times to retry. The Notifications feature enables you to receive timely notifications without logging in to the VMware Pulse IoT Center, or without providing an integration point into the existing monitoring systems. The Notifications feature acts as a primary interface for all HTTP and email (SMTP) notifications from the VMware Pulse IoT Center server. All the other VMware Pulse IoT Center services communicate with the notifications service to send notifications to the external servers.
