SQL Server Transactions Per Day
This post can help you in capturing SQL Server Transactions per day. Sometimes we need to capture the average number of transactions per day / hour / minute. Below is the T-SQL script that can help you to capture the SQL Server Transactions per day. Below script returns two result sets:
- Retrieves the total transactions occurred in SQL Server Instance since last restart
- Database Wise Average Transactions since last restart
T-SQL to capture SQL Server Transactions per day:
/************************************************************/ /******* SQL Server Transactions Per Day / Hour / Min *******/ /******* Tested : SQL Server 2008 R2, 2012, 2014 ************/ /******* Author : udayarumilli.com **************************/ /************************************************************/ DECLARE @Days SMALLINT, @Hours INT, @Minutes BIGINT, @Restarted_Date DATETIME; /*** Capture the SQL Server instance last restart date ***/ /*** We will gte the Tempdb creation date ***/ SELECT @Days = DATEDIFF(D, create_date, GETDATE()), @Restarted_Date = create_date FROM sys.databases WHERE database_id = 2; /*** Prepare Number of Days and Hours Since the last SQL Server restart ***/ SELECT @Days = CASE WHEN @Days = 0 THEN 1 ELSE @Days END; SELECT @Hours = @Days * 24; SELECT @Minutes = @Hours * 60; /*** Retrieve the total transactions occurred in SQL Server Instance since last restart ***/ SELECT @Restarted_Date AS 'Last_Restarted_On', @@SERVERNAME AS 'Instance_Name', cntr_value AS 'Total_Trans_Since_Last_Restart', cntr_value / @Days AS 'Avg_Trans_Per_Day', cntr_value / @Hours AS 'Avg_Trans_Per_Hour', cntr_value / @Minutes AS 'Avg_Trans_Per_Min' FROM sys.dm_os_performance_counters WHERE counter_name = 'Transactions/sec' AND instance_name = '_Total'; /*** Database Wise Average Transactions since last restart ***/ SELECT @Restarted_Date AS 'Last_Restarted_On', @@SERVERNAME AS 'Instance_Name', instance_name AS 'Database_Name', cntr_value AS 'Total_Trans_Since_Last_Restart', cntr_value / @Days AS 'Avg_Trans_Per_Day', cntr_value / @Hours AS 'Avg_Trans_Per_Hour', cntr_value / @Minutes AS 'Avg_Trans_Per_Min' FROM sys.dm_os_performance_counters WHERE counter_name = 'Transactions/sec' AND instance_name <> '_Total' ORDER BY cntr_value DESC;
Here is the script file: SQL_Server_Transactions_Per_Day
These are the average values. To get the exact transaction details we can automate the capture process:
- Create a table to capture the transaction counts since last restart
- Create a stored procedure to capture the transactions since the last restart
- Schedule a job to execute the procedure on hourly basis
- Write a query to capture the hourly differences
