This article describes how to set up the Microsoft IIS W3C Advanced Logging connector for LEM.
Note: If X-Forward Log field is not showing up in LEM web console, then make sure the "Microsoft IIS Web Server 5.0 (W3C Extended file format)" connecter version is #41
Contact SolarWinds Technical Support if this does not cause the Advanced IIS logs to begin showing up on the LEM.
