SQL SERVER script to Identify Currently Running Queries


There might be situations where u might be getting requests from users saying that the entire website is slow or the application is slow. Situations like these could be because of a slow running query where users might have an impression of the enire server being slow and u might be getting Support Tickets related to that. Well Situations like these may demand you to look into some currently running queries on the server. Sometimes these currenty running queries may be long running queries may even be the cause for a complete server slowness depending on your isolation levels.

If we could identify all the currently running queries or keep monitoring the queries wich are run we can identify a bad query and determine if that could be a bad query

In the image below shown the query is run on my personal laptop where no currently running queries are present. However when u run the same on a production machine you will get a lot of queries being displayed in the results.
