Database Autonomy Service (DAS) provides the autonomy center feature for ApsaraDB RDS for MySQL. You can enable the autonomy center feature for your ApsaraDB RDS for MySQL instance to query events that occurred within a specified time range. The events include exceptions, optimization events, and auto scaling events.
Your RDS instance runs one of the following MySQL versions and RDS editions:
MySQL 8.0 on RDS High-availability Edition, RDS Enterprise Edition, or RDS Cluster Edition
MySQL 5.7 on RDS High-availability Edition, RDS Enterprise Edition, or RDS Cluster Edition
MySQL 5.6 on RDS High-availability Edition
MySQL 5.5 on RDS High-availability Edition
DAS monitors the core metrics of your RDS instance to detect anomalies. If an anomaly is detected, DAS checks sessions, SQL statements, and the capacity of the RDS instance to identify the cause. DAS also provides suggestions on how to optimize performance or mitigate the loss. You can authorize DAS to automatically optimize performance or mitigate the loss.
