title: Azure application gateway firewall logs not being populated to log analytics workspace
body: <p>We have provisioned the instance of the Azure app gateway (Standard v2 East AU region) and has enabled the diagnostics settings of it to dump all metrics and logs to the log analytics workspace and this seem to be working fine, however we wanted to additional insights of the request and hence have scaled up the tier and enabled the WAF v2 (as shown in the image below). </p>

  <p>Now based on this documentation here <a href="https://docs.microsoft.com/en-us/azure/application-gateway/application-gateway-diagnostics#diagnostic-logging" rel="nofollow noreferrer">https://docs.microsoft.com/en-us/azure/application-gateway/application-gateway-diagnostics#diagnostic-logging</a> and after waiting for some time, we expected that the firewall logs will be automatically populating in the same log analytics workspace however this does not seem to work and they are simply not populated there.</p>
  
  <p>Note that we can see the "ApplicationGatewayAccessLog" logs and below query is evident of the same AzureDiagnostics | distinct  Category that returns only one category i.e. "ApplicationGatewayAccessLog"</p>
  
  <p>Does anyone know if we are missing something or have any input? </p>
