Hello We recently encountered an issue where a SQL table unexpectedly grew in size due to an application error. The table increased from a few gigabytes to around 11 TB within one week, which completely filled the PRIMARY filegroup. To prevent this from happening again, I would like to set up an alerting system that notifies us when the database or filegroup reaches 80% usage. My question is: Is there a built-in alerting mechanism in SQL Server that can trigger an alert when a filegroup or database exceeds a specific usage threshold? Or do we need to implement a custom solution (SQL Agent job, Extended Events, external monitoring tool, etc.)? Thank you in advance for your help.
