Viewing the Size of Log Files in SQL Server

Hello everyone,

In this article, I will provide information about viewing the size of log files in SQL Server.

In SQL Server we may want to view the size of log files in some cases.

You can easily do this with the help of the code below.

SELECT DB_NAME(mf.database_id) AS 'DB Name',
       name AS 'File Logical Name',
       'File Type' = CASE
                         WHEN type_desc = 'LOG' THEN
                             'Log File'
                         WHEN type_desc = 'ROWS' THEN
                             'Data File'
                         ELSE
                             type_desc
                     END,
       mf.physical_name AS 'File Physical Name',
       size_on_disk_bytes / 1024 AS 'Size(KB)',
       size_on_disk_bytes / 1024 / 1024 AS 'Size(MB)',
       size_on_disk_bytes / 1024 / 1024 / 1024 AS 'Size(GB)'
FROM sys.dm_io_virtual_file_stats(NULL, NULL) AS divfs
    JOIN sys.master_files AS mf
        ON mf.database_id = divfs.database_id
           AND mf.file_id = divfs.file_id
WHERE CASE
          WHEN type_desc = 'LOG' THEN
              'Log File'
          WHEN type_desc = 'ROWS' THEN
              'Data File'
          ELSE
              type_desc
      END = 'Log File'
ORDER BY DB_NAME(mf.database_id);

When you run the code, you will get a result like the one below.

As you can see, the size of the log files is displayed.

Good luck to everyone in business and life.
