The capacity assessment feature provides detailed storage usage reports and predictive storage usage analysis, including real-time storage usage and storage usage trends based on machine learning and capacity algorithms. This topic describes how to use the capacity assessment feature when you make decisions on how to optimize the storage capability of an ApsaraDB RDS for MySQL instance and plan storage capacity expansion.
Prerequisites
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
Procedure
- Go to the Instances page. In the top navigation bar, select the region in which the RDS instance resides. Then, find the RDS instance and click the ID of the instance.
In the left-side navigation pane, choose Autonomy Services > Diagnostics.
Click the Capacity Assessment tab.
Perform the following operations in the following sections:
Capacity Suggestion: Check the values of Status and Suggestion.
Capacity Assessment: View the storage performance and the storage usage within a specific time range.
