In the autonomy center of Database Autonomy Service (DAS), you can query the events that occurred within a specified time range. The events are categorized into exceptional events, 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 analyzes sessions, SQL statements, and the instance capacity to identify the cause. Then, DAS provides suggestions on performance optimization to mitigate the loss. You can authorize DAS to automatically optimize the performance to mitigate the loss.


The database instance that you want to manage is an ApsaraDB RDS for MySQL instance or an ApsaraDB PolarDB MySQL-compatible edition instance.
