Event Notification Overview

Overview

DIS uses Simple Message Notification (SMN) to send notifications of DIS events. In a subscription, you need to specify one or more event filtering conditions. When an event that matches all filtering conditions occurs, DIS sends a notification based on the subscription. The filter conditions include the Event Type (for example, Management, Monitoring, or Security), Event Level (for example, Normal or Warning), and Event Source (for example, Stream, Dump task, or User).

Supported Event Types and Events

Events are records of changes in the tenant's stream status. It can be triggered by a user operation (for example, an audit event), or may be caused by a stream status change (for example, a dump task is abnormal or a dump task is recovered). The following tables list the events and event types supported by DIS:
