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


The destination database instance is a PolarDB for MySQL cluster.
