Viewing GaussDB(DWS) Cluster 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). GaussDB(DWS) supports the following event types: Cluster Events, Snapshot Events, Disaster Recovery Events, and Data Migration Events. Generally, normal events do not require human intervention. For warning events, you need to check whether related operations are normal. You can handle them by referring to Management Console Error Code.
Viewing Events
- Log in to the DWS console.
- In the navigation pane on the left, choose Dedicated Clusters > Management > Events.
On the Events page, all the events that have occurred in all clusters or snapshots are displayed by default.
You can sort the events in descending or ascending order by clicking
next to Time.
You can search for events by time, event, event level, event source, event source type, or event type using the search box at the top of the event list.Figure 1 Events page
