         answer: |
           Flow logs enable you to log 5-tuple flow information about your Azure IP traffic that passes through a network security group or Azure virtual network. The raw flow logs are written to an Azure storage account. From there, you can further process, analyze, query, or export them as needed.

           Network Watcher has a built-in fallback mechanism that it uses when connecting to a storage account behind a firewall (firewall enabled). It tries to connect to the storage account using a key, and if that fails, it switches to a token. In this case, a 403 error is logged in the storage account activity log.
