sp_Blitz Result: Failsafe Operator Not Configured
A fail safe operator is used if any of the default notification operators are not available. The fail safe operator can also send out alerts if there are issues with the msdb database.
This part of our SQL Server sp_Blitz script checks sp_MSgetalertinfo to make sure failsafe operators are configured.
