Inspection and scoring - Database Autonomy Service - Alibaba Cloud Documentation Center

Database Autonomy Service (DAS) provides the inspection and scoring feature. This feature inspects and scores all database instances on a daily basis. DAS also allows you to specify database instances and inspection periods and manually initiate inspection and scoring. This helps you understand the status of database instances.

Prerequisites

One of the following database instances is available for inspection and scoring:
- ApsaraDB RDS for MySQL
- Self-managed MySQL database
- PolarDB for MySQL
- ApsaraDB MyBase for MySQL
- ApsaraDB for Redis
The database instance is connected to DAS and is in the Accessed state. For more information, see Connect an Alibaba Cloud database instance to DAS.
