SQL Server Data Management Report - Get Drive Size and Drive Free Space
One of the regular DBA practice is to maintain the free space on Drives where the data files are located.
Here i have created a script (Space Management) which gives us the database files, its location,size, growth rate, the drive where its located, drive size, drive free space etc...
Most of the thing is very easy to retrieve through SQL Queries as those are maintained in tables under msdb databases, but the free space and size of drive is something which require system interaction using master..xp_cmdshell and that part of query is a bit complex :
-- -- To allow advanced options to be changed.
EXEC sp_configure 'show advanced options', 1
GO
-- To update the currently configured value for advanced options.
RECONFIGURE
GO
-- To enable the feature.
EXEC sp_configure 'xp_cmdshell', 1
GO
-- To update the currently configured value for this feature.
RECONFIGURE
GO

Step2: Excute the following script
declare @Drive table(DriveName char,freespace decimal(9,2), totalspace decimal(9,2),percentfree decimal(9,2))
BEGIN
SET NOCOUNT ON;
DECLARE @v_cmd nvarchar(255)
,@v_drive char(99)
,@v_sql nvarchar(255)
,@i int
SELECT @v_cmd = 'fsutil volume diskfree %d%'
SET @i = 1
-- Creating temporary tables to retrive system space information.
CREATE TABLE #drives(iddrive smallint ,drive char(99))
CREATE TABLE #temp1(drive char(99),shellCmd nvarchar(500));
CREATE TABLE #results(drive char(99),freespace decimal(9,2), totalspace decimal(9,2));
INSERT #drives (drive)
EXEC master..xp_cmdshell 'mountvol'
DELETE #drives WHERE drive not like '%:\%' or drive is null
WHILE (@i <= (SELECT count(drive) FROM #drives))
BEGIN
UPDATE #drives
SET iddrive=@i
WHERE drive = (SELECT TOP 1 drive FROM #drives WHERE iddrive IS NULL)
SELECT @v_sql = REPLACE(@v_cmd,'%d%',LTRIM(RTRIM(drive))) from #drives where iddrive=@i
INSERT #temp1(shellCmd)
EXEC master..xp_cmdshell @v_sql
UPDATE #temp1
SET #temp1.drive = d.drive
FROM #drives d
WHERE #temp1.drive IS NULL and iddrive=@i
SET @i = @i + 1
END
INSERT INTO #results
SELECT bb.drive
,CAST(CAST(REPLACE(REPLACE(SUBSTRING(shellCmd,CHARINDEX(':',shellCmd)+1,LEN(shellCmd)),SPACE(1),SPACE(0))
,char(13),SPACE(0)) AS NUMERIC(32,2))/1024/1024/1024 AS DECIMAL(9,2)) as freespace
,tt.titi as total
FROM #temp1 bb
JOIN (SELECT drive

,char(13),SPACE(0)) AS NUMERIC(32,2))/1024/1024/1024 AS DECIMAL(9,2)) as titi
FROM #temp1
WHERE drive IS NOT NULL
AND shellCmd NOT LIKE '%free bytes%') tt
ON bb.drive = tt.drive
WHERE bb.drive IS NOT NULL
AND bb.shellCmd NOT LIKE '%avail free bytes%'
AND bb.shellCmd LIKE '%free bytes%';
-- getting all system specific formatted data into @Drive table
INSERT INTO @Drive
SELECT LEFT(RTRIM(LTRIM(drive)),1) as drive
,freespace
,totalspace
,CAST((freespace/totalspace * 100) AS DECIMAL(5,2)) as [percent free]
FROM #results
ORDER BY drive
-- Dropping temporary tables
DROP TABLE #drives
DROP TABLE #temp1
DROP TABLE #results
SELECT
@@Servername as Server,
sd.name as Database_name,
mas.name as File_Name,
mas.size * 8 / 1024 File_Size_MB,
CASE [is_percent_growth]
WHEN 1 THEN CAST(mas.growth AS varchar(20)) + '%'
ELSE CAST(mas.growth*8/1024 AS varchar(20)) + ' MB'
END as Growth_rate,
drv.DriveName as Drive_Name,
drv.FreeSpace,
drv.totalspace,
CASE type
WHEN 0 THEN 'Data'
WHEN 1 THEN 'Log'
END as File_type,
mas.physical_name as File_Location
FROM sys.master_files mas
LEFT JOIN @Drive drv ON LEFT(mas.physical_name, 1) = drv.DriveName
LEFT JOIN sys.databases sd ON mas.database_id = sd.database_id
--WHERE sd.name IN ('db1','db2','db3') -- Specify the database name if this report is needed for specific databases
--AND mas.growth <>0 -- Condition to retrive the record for growing files only.
END

- You can restrict the output for some of the databases by providing the database name which is commented by default.
--WHERE sd.name IN ('db1','db2','db3')
- You can also restrict the output for growing files of the databases only by providing the growth <>0 which is commented by default.
There are further filters also possible like if someone want to restrict the query upto a size limit of files etc. simply write it down in where clause.
Output:
Output should be like this:
This could be very useful where someone have multiple servers and DBA has to generate weekly/Monthly report for all of the server, in such scenario one can create a SSIS package and execute this query on all the server and generate a single report for all the servers.
Hope this will be helpful for people out there :) let me know if anyone has any issue.
