SQL Server Management Studio offers a lot of tools to track what a spid is doing and how it affects the sql server and other spids. Some of the tools can offer information at a very granular level while others to an wider level. Because sometimes we just want something between we need to use what Microsoft offers and use it appropriately. To have an overview of a specifc spid we can use:
- built in dmv
- Activity Monitor
- extended events
Or we can use custom script that will aggregate information using Microsoft dmvs and SPs and present them. The biggest advantage of using custom scripts is that we can choose
- to display results to text
- to display columns as rows
- to create a include client statistics look like
Microsoft is already doing this when we choose Query – Include Client Statistics which is why I decided to duplicate that and show status,blocking_session_id,wait_type,wait_duration_ms,cpu_time,memory_usage,total_scheduled_time,reads,writes,logical_reads,arithabort,transaction_isolation_level,lock_timeout,deadlock_priority
The output looks like below and I want to mention before anything else that the script used is providing a broad overview and was created on spot only to test how the output look like. Because of this
- The output should be read and understood from this perspective.
- The script and the way was written should be seen from this perspective also.
The values that I choose to show are not the most important and they were choose only to show that by choosing to display columns like status we decrease the amount of info that can fit but we can code some of the columns using numeric values, 1 for running, 2 for sleeping and so on. The biggest advantage of this type of display is that we can see how specific spid behave up and down by having only one look throughout of execution time.
Depending on the things that you want to track you can create your own script using the script below as an example. The only thing that you need to check is Results to Text in SSMS.
