I opened a support ticket and with their help I was able to solve the problem.

 

I had to go to the Log Analytics Workspace, to which I configured the application gateway to send its log too. There I could query for the logs and all tables were in place.

 

What I did before was going to:  "Application Gateway Resource -> Monitoring -> log" 

The log there is empty and missing tables and is not connected to the Log Analytics Workspace I created on the gateway resource.

This is a kind of confusing UI design, but now I know how to access/query the log.

 

Thanks again for your input.

Hi,
It seems like you did the right things and it should work without going to the workspace. I will investigate what happened in your case.

Sorry for that,
Meir from the Azure Monitor Logs team

        Meir_MendelovichI have various VMs which are reporting logs to a Log Analytics Workspace, but when I go to the 'logs' link under the VM, it does not send me to that LAW. When I attempt to query against the logs from that location, I get the same error described above. I can go directly to the assigned LAW, and query against the logs normally.
