Viewing Top Databases and Tables by Physical File Size

In combination with disk space distribution, top 50 databases and tables by physical file size help you identify the databases and tables with high disk space usage.

Procedure

Log in to the management console.
Click in the upper left corner of the page and choose Databases > Relational Database Service.
On the Instances page, click the target DB instance name to go to the Overview page.
In the navigation pane, choose DBA Assistant > Real-Time Diagnosis and click the Storage Analysis tab.
On the Storage Analysis page, view the top 50 databases and tables in the Top Databases and Tables area.
- Physical file sizes are precisely recorded, but other fields' values are estimated. If there is a large gap between a file size and another field, run ANALYZE TABLE on the table.
- A database or table whose name contains reserved special characters, including slashes (/) and #p#p, is not counted. #p#p identifies the table as a partitioned table.
- If there are more than 50,000 tables in your instance, to prevent data collection from affecting the instance performance, top databases and tables will not be counted.
Locate a database and click View Chart in the Operation column. You can view data volume changes in the last 7 days, last 30 days, or a custom time period (spanning no more than 30 days).
