Metrics install automatically if you have Redgate Monitor installed.

If you are using Redgate’s SQL Server monitoring tool, Redgate Monitor, you can instantly install and run this metric on your servers.

This metric reports the total space used by database files in GB. This includes data files but excludes log files.

This lets you track the growth of the databases over time so you can be aware of future space requirements.

Alternatively, the following T-SQL can be used for SQL Server 2012 and higher:

SELECT CAST(SUM(allocated_extent_page_count * 8.0 / 1024. / 1024.) AS DECIMAL(18,6)) AS Allocated_GB
FROM sys.dm_db_file_space_usage;

1 2	SELECT CAST(SUM(allocated_extent_page_count * 8.0 / 1024. / 1024.) AS DECIMAL(18,6)) AS Allocated_GB FROM sys.dm_db_file_space_usage;
