Different ways to get the size of the data , log files and Databases
- Using Counters
- Querying sysaltfiles & sys.databases
- Querying sys.master_files
SELECT instance_name AS DatabaseName,
[Data File(s) Size (KB)]/1024.00 [DataInMB],
[LOG File(s) Size (KB)]/1024.00 [LogInMB],
[Data File(s) Size (KB)]/1024.00 + [LOG File(s) Size (KB)]/1024.00 [TotalSize]
FROM
(
SELECT *
FROM sys.dm_os_performance_counters
WHERE counter_name IN ('Data File(s) Size (KB)', 'Log File(s) Size (KB)' )
AND instance_name != '_Total'
) AS Src
PIVOT
(
MAX(cntr_value)
FOR counter_name IN
( [Data File(s) Size (KB)], [LOG File(s) Size (KB)] )
)AS pvt
USE MASTER Go SELECT CONVERT(VARCHAR(25), DB.name) AS DatabaseName, (SELECT SUM((size*8)/1024.00) FROM sysaltfiles WHERE DB_NAME(dbid) = DB.name AND groupid!=0) AS [Data MB], (SELECT SUM((size*8)/1024.00) FROM sysaltfiles WHERE DB_NAME(dbid) = DB.name AND groupid=0) AS [Log MB], (SELECT SUM((size*8)/1024.00) FROM sysaltfiles WHERE DB_NAME(dbid) = DB.name AND groupid!=0)+(SELECT SUM((size*8)/1024.00) FROM sysaltfiles WHERE DB_NAME(dbid) = DB.name AND groupid=0) TotalSizeMB FROM sys.databases DB ORDER BY DatabaseName
SELECT DatabaseName = DB_NAME(database_id) ,[Data MB] = CAST(SUM(CASE WHEN type_desc = 'ROWS' THEN size END) * 8. / 1024 AS DECIMAL(8,2)) ,[Log MB] = CAST(SUM(CASE WHEN type_desc = 'LOG' THEN size END) * 8. / 1024 AS DECIMAL(8,2)) , [TotalSizeMB] = CAST(SUM(size) * 8. / 1024 AS DECIMAL(8,2)) FROM sys.master_files GROUP BY database_id ORDER BY DatabaseName

Hi Prashanth,
we have power shell script for data base size, Data file free space available,log size and log file free space.
I need ur help for getting result for Log file free space.
