In the autonomy center of Database Autonomy Service (DAS), you can query events that occurred within a specified time range. These events include exceptions, optimization events, auto scaling events, and other events. DAS monitors the core metrics of a database instance to detect anomalies. If an anomaly is detected, DAS checks sessions, SQL statements, and the capacity of the database instance to identify the cause. Then, DAS provides suggestions on how to optimize performance to mitigate the loss. You can authorize DAS to automatically optimize performance to mitigate the loss.


The instance that you want to manage is an ApsaraDB RDS for MySQL instance or a PolarDB for MySQL instance.
