In the "Actions" Pane of IIS Manager (InetMgr), under Configure there is supposed to be a link for Failed Request Tracing.

I don't see that... I just have "Limits..."?

Install the Tracing component of the Web Server role through Server Manager.

It's in the Web Server (IIS) -> Health and Diagnostics area on all IIS versions from 7 up.

Add Roles and Features Wizard on Windows Server 2016 (By the way: Whenever you add a component to IIS, you need to restart the IIS Manager GUI, to reload the UI modules. This doesn't apply to most other changes, because they happen "live" - it's just the user interface module list which is cached at startup.)

Failed Request Tracing then shows up in the Actions Pane at the Site level, and needs to be enabled there before rules will fire.

Then, you configure your Failed Request Tracing rules at any level within that site to capture what you want.

    +1 for the Configure screenshot - Azure was putting the logs on TempLocalStorage of course, not at the default location – d.popov Sep 19 '17 at 06:46
