sp_WhoIsActive

sp_WhoIsActive is a comprehensive activity monitoring stored procedure that works for all versions of SQL Server from 2005 through 2022 and Azure SQL DB.

sp_WhoIsActive is now officially versioned and maintained here on GitHub.

The license is now GPLv3.

Documentation is still available at http://whoisactive.com/docs

If you have enhancements, please consider a PR instead of a fork. I would like to continue to maintain this project for the community.

Installation instructions

Download the script sp_WhoIsActive.sql from this root folder, open it in SQL Server Management Studio, and run it!

[!TIP] The script will run in the database of the current connected session. If you want, you can change the database to master so the procedure will be available to run from every database in the instance.

Previous version compatibility

The script root folder is focused on supporting the latest SQL Server release features and compatibility. To use it with older versions, do the following:

• For 2012 to 2019, use the sp_WhoIsActive.sql from the 2019 folder
• For 2008 or earlier, use the sp_WhoIsActive.sql from the 2008 folder

Going forward new folders will be created every two versions, so that the script can continue to grow and mature with SQL Server.

Script version numbering

Version numbering indicates the minimum and maximum supported versions, and the release date, in the following format: vAABB.YYYYMMDD

AA and BB represent minimum and maximum supported SQL Server release years in the 2000s. YYYYMMDD is the date of the sp_whoisactive release.

So v1219.20260419 means the script that targets SQL Server 2012-2019, with a release date of 2026-04-19.

The current version will always have a 00 for the BB portion, indicating its support for some number of future versions. (Ideally one to two, as noted in the previous version compatibility section.)
