I enabled NSG flow logs for one of the network security group in our subscription and configured separate storage account to store the logs and enabled Traffic Analytics to watch flow logs in network watcher Traffic Analytics.

Able to see nsg flow logs in configured storage account.
But those were not visible in network watcher.

The message is like below.
Looks like we have only resources data (Topology) and no flow info for the selected workspace.

It is almost week back configured these but still same message.
Any suggestions

    Have you definitely enabled traffic analytics also? You need to deploy a log analytics workspace to ingest the NSG logs. Please see this part of the documentation here for the complete setup guide: https://learn.microsoft.com/en-us/azure/network-watcher/traffic-analytics#enable-flow-log-settings

    If you have done this already, you can check the logs in the log analytics workspace and see if any data has been ingested but it sounds like this is the issue.
