So I set about looking for a workaround. This week I think I’ve finally managed to get something working that approximates the number I need from that view, ms_ticks.
Attached is sp_whoisactive v11.112 — Azure Special Edition v2. Please give it a shot, and I am especially interested in feedback if you use the @get_task_info = 2 option when running sp_whoisactive. That is the main use case that’s impacted by the lack of ms_ticks information and my attempt at a workaround.
If you’re using on-prem SQL Server, this doesn’t add anything new, but if you’re on Azure SQL Database, give it a try.
