Database Autonomy Service (DAS) provides the capacity assessment feature. You can view suggestions on capacity optimization, performance capacity statistics, storage usage, and the number of remaining days for which the storage is available. This feature uses machine learning and capacity algorithms to predict future storage usage.


The database instance that you want to manage is an ApsaraDB RDS for MySQL instance.


  1. Log on to the DAS console.
  2. In the left-side navigation pane, click Capacity Assessment.
  3. On the Capacity Assessment tab, you can view the statistics about storage performance and storage usage in the Capacity Suggestion and Capacity Assessment sections.
