Event Notifications Overview

Overview

GaussDB(DWS) uses the Simple Message Notification (SMN) service to send notifications of GaussDB(DWS) events. The SMN function is only available by subscription. In a subscription, you need to specify one or more event filtering conditions. When an event that matches all filtering conditions occurs, GaussDB(DWS) sends a notification based on the subscription. The filter conditions include the Event Type (for example, Management, Monitoring, or Security), Event Severity (for example, Normal or Warning), and Event Source Category (for example, Cluster or Snapshot).

Supported Event Types and Events

Events are records of changes in the user's cluster status. Events can be triggered by user operations (such as audit events), or may be caused by cluster service status changes (for example, cluster repaired successfully or failed to repair the cluster). The following tables list the events and event types supported by GaussDB(DWS).

  • The following table lists the events whose Event Source Category is Cluster.
