Question

I need to persist all IIS logs automatically in Azure storage, how to enable it?

I see that there are different properties in DiagnosticMonitorConfiguration class, e.g. DiagnosticInfrastructureLogs, Logs, Directories, etc. Which of the above is responsible for the IIS logs? What blob/table are the logs stored to?

Thanks!

Under Directory Buffers, you have two options.. IIS Logs and Failed RequestLogs.

Here’s a snippet from the diagnostic schema definition that outlines these options:

   <Directories bufferQuotaInMB="1024" 
  scheduledTransferPeriod="PT1M">

  <!-- These three elements specify the special directories 
       that are set up for the log types -->
  <CrashDumps container="wad-crash-dumps" directoryQuotaInMB="256" />
  <FailedRequestLogs container="wad-frq" directoryQuotaInMB="256" />
  <IISLogs container="wad-iis" directoryQuotaInMB="256" />

  <!-- For regular directories the DataSources element is used -->
  <DataSources>
     <DirectoryConfiguration container="wad-panther" directoryQuotaInMB="128">
        <!-- Absolute specifies an absolute path with optional environment expansion -->
        <Absolute expandEnvironment="true" path="%SystemRoot%\system32\sysprep\Panther" />
     </DirectoryConfiguration>
     <DirectoryConfiguration container="wad-custom" directoryQuotaInMB="128">
        <!-- LocalResource specifies a path relative to a local 
             resource defined in the service definition -->
        <LocalResource name="MyLoggingLocalResource" relativePath="logs" />
     </DirectoryConfiguration>
  </DataSources>
