The Autonomy Center of Database Autonomy Service (DAS) displays abnormal events, optimization events, auto scaling events, and other events within a specified time range.
Prerequisites
The target database instance is one of the following types:
-
ApsaraDB RDS for MySQL

Features
DAS performs anomaly detection by monitoring the core metrics of your database instance. If an anomaly is detected, DAS automatically runs diagnostics on sessions, SQL statements, and capacity to identify the root cause. It then provides actionable recommendations for optimization or mitigation. If you grant the necessary permissions, DAS can also perform these actions automatically.
