AzureNetworkAnalytics_CL not being populated after creating v2 NSG Flow Logs with Traffic Analysis

Josh Madakor 5 Reputation points

After configuring v2 NSG Flow Logs with Analytics enabled, the AzureNetworkAnalytics_CL table will not even be created within the target Log Analytics Workspace. I have tried deleting the whole network watcher resource, NSGs, diagnostic settings, and flow logs and re-creating them, but the 'AzureNetworkAnalytics_CL' table will NOT create. This is happening in more than one tenant

    Hello @Josh Madakor ,


    Thanks for reaching out to the Q and A platform.


    Please make sure that you are running the Query on the right Log Analytics workspace, that has been attached in the NSG flow log.


    Here is the observation on the lab I have created.


    Flow Log been created:

    Which has been attached to the workspace as mentioned below, and its Version 2 flow log:

    Now running the query on the workspace:

    I have a workspace, where it is not attached to the NSG flow log, there I could see that AzureNetworkAnalytics_CL not been recognized.
