Function Overview

Description

DBA Assistant provides visualized database O&M and intelligent diagnosis for developers and database administrators (DBAs), making database O&M easy and efficient. By analyzing alarms, resource usage, health status, performance metrics, and storage usage, it helps you quickly locate faults and keep track of instance statuses.

To use DBA Assistant on the GaussDB(for MySQL) console, you need to ensure that IAM users must have the GaussDB FullAccess, DAS FullAccess, DAS Administrator, and CES FullAccess permissions. For details, see Creating a User and Granting GaussDB(for MySQL) Permissions.
