In the past, it was possible to setup an Azure alert on a single event for a resource e.g. on data factory single RunFinished where the status is Failed*.
This appears to have been superseded by "Activity Log Alerts"
However these alerts only seem to either work on a metric threshold (e.g. number of failures in 5 minutes) or on events which are related to the general admin of the resource (e.g. has it been deployed) not on the operations of the resource.
A threshold doesn't make sense for data factory, as a data factory may only run once a day, if a failure happens and then it doesn't happen X minutes later it doesn't mean it's been resolved.
The activity event alerts, don't seem to have things like failures.
Am I missing something?
It it because this is expected to be done in OMS Log Analytics now? Or perhaps even in Event Grid later?
*n.b. it is still possible to create these alert types via ARM templates, but you can't see them in the portal anymore.
