How to check transaction log size in sql server

Answer 1

To check the transaction log size in SQL Server, use the DBCC SQLPERF (logspace) command in SQL Server Management Studio, which shows the current log size and usage percentage.

Step-by-step explanation:

To check the transaction log size in SQL Server, you can use the built-in function DBCC SQLPERF (logspace). This function provides information about the size and space usage of the transaction log. Here's how you can use it:

1. Open SQL Server Management Studio (SSMS).
2. Connect to the relevant SQL Server instance.
3. Open a new query window.
4. Run the following command: DBCC SQLPERF(logspace).
5. Review the results, which will include the current size of the log and the percentage used.

Additionally, if you need more detailed information, you can use sys.dm_db_log_space_usage dynamic management view (DMV) in SQL Server 2016 or later. If you have SQL Server 2012 or earlier, you may query the sys.database_files catalog view where you can find the size by filtering on the file type for log file using the type_desc column.
