Configure virtual networks to enforce workspace, storage account and retention interval for Flow logs and Traffic Analytics: Needs to assess Microsoft.Network/networkWatchers/flowLogs/provisioningState

[jcetina]

Details of the scenario you tried and the problem that is occurring

Flow logs can fail to provision correctly sometimes (we don't know why - they just do). When provisioning state fails, it is reflected in the JSON representation of the flowLog resource in properties.provisioningState. If this field does not equal Succeeded, then the resource is not correctly provisioned.

Verbose logs showing the problem

This is the only indication of error we get in Activity Logs.
