RDS for Mysql(ver 5.7.38)　For unknown storage space

The actual data used by innodb does not match the storage usage that I can see in the metrics.

The real data is checked with ALLOCATED_SIZE in the following query.

SELECT NAME,FILE_SIZE,ALLOCATED_SIZE FROM information_schema.innodb_sys_tablespaces

In addition to this, log data and fragment data were also checked, but even when they were added, there was still an overwhelming difference.

Is there any other way to check the space allocated by RDS?
