Looking for some ideas and/or approaches to analyze the queries, stored procedures etc that my database support department is running over time. My hope is to gain insight into the tables, rows, columns and stored procedures etc. being run to solve day to day data problems from our ticketing queue. For obvious reasons!!! this i believe will be helpful in targeting and eliminating root cause and thus reducing our load and customer facing issues that cause user frustration.

thanks,
dave

1.create the table first  to store the data

CREATE TABLE [dbo].[longrunning](
      [session_id] [int] NULL,
      [start_time] [datetime] NULL,
      [status] [varchar](max) NULL,
      [cpu_time] [int] NULL,
      [Elapsed time(ms)] [int] NULL,
      [sql_statement] [nvarchar](max) NULL,
      [host_name] [varchar](100) NULL,
      [program_name] [varchar](100) NULL
) ON [PRIMARY]
 
2.Use the below sproc and set it up as job to run may be every 5 minutes or so.The query will record anything that goes beyond 2 secs. You can increase the time according to your need
 

CREATE procedure [dbo].[usp_longrunningqueries] --- Added Logic to ignore blocking by same SPID's which is identified as normal using parrellelism    
as    
begin    
 insert into longrunning(    
 session_id,  
 start_time,  
 status,  
 cpu_time,  
 [Elapsed time(ms)],  
 sql_statement,  
 host_name,  
 program_name)    
 SELECT  p.session_id, start_time, p.status,p.cpu_time,p.total_elapsed_time, --original_login_name,  
    (SELECT TOP 1 SUBSTRING(s2.text,statement_start_offset / 2+1 ,( (CASE WHEN statement_end_offset = -1  
    THEN (LEN(CONVERT(nvarchar(max),s2.text)) * 2)  
    ELSE statement_end_offset END)  - statement_start_offset) / 2+1))  AS sql_statement,host_name,program_name  --INTO longrunning  
 FROM sys.dm_exec_requests p  
 CROSS APPLY sys.dm_exec_sql_text(sql_handle)  s2 inner join sys.dm_exec_sessions s on s.session_id=p.session_id  
 AND p.total_elapsed_time > 2000--(2 sec)  

end

There are 3 'tracking' type areas of functionality in SQL Server 2008
1. Change Data Capture
http://blog.sqlauthority.com/2009/08/15/sql-server-introduction-to-change-data-capture-cdc-in-sql-server-2008/

2. Change Tracking
http://www.mssqltips.com/sqlservertip/1819/using-change-tracking-in-sql-server-2008/

3. SQL Server Audit
http://www.bradmcgehee.com/2010/03/an-introduction-to-sql-server-2008-audit/

These may be worth exploring as they may give some of the monitoring that you need to build up a picture of what users are doing.

I looked into SQL Audit myself a couple of months ago as a possibility for monitoring activity on a 'development' version of a Data Warehouse.
It seemed to be reasonably quick and straightforward to switch on and it gave nice 'log' type information which could be viewed just like any other SQL Server log.
