It's been noticed that MSSQL Extension is not having an important metric of DB size. That is available in Oracle Extension.
Please raise an ER for the same. Possible queries below:
exec sp_spaceused
or
EXEC sp_helpdb @dbname= 'DB_NAME'
or
SELECT
DB_NAME() AS [database_name],
CAST(SUM(
CAST( (size * 8.0/1024) AS DECIMAL(15,0) )
) AS VARCHAR(20)) AS [database_size(MB)]
FROM sys.database_files;
Created a customer ER defect for further triage and prioritization:
DE604291: - Enhancement request to add DB Size in MSSQL Extension
SQL Server 14-18 is supported for these metrics but not SQL Server 13.
