Viewing Instance Overview Data

Scenarios

You can view information about created DB instances, including instance statuses and alarm statistics.

To apply for the permissions needed, submit an application by choosing Service Tickets > Create Service Ticket in the upper right corner of the management console.

Procedure

1. Log in to the management console.
2. Click in the upper left corner and select a region and project.
3. Click in the upper left corner of the page and choose Databases > GaussDB.
4. In the navigation pane, choose Overview.
   

   If there are no DB instances, no DB instance information will be displayed on the Overview page. Instead, you can only create a DB instance on this page.

   If you are a new user, create a DB instance as prompted. If there are existing instances, you can view instance information on this page.
