Hi, everyone. I'm new to this forum, so forgive me for any obvious blunders.
I'm having trouble getting any output from Failed Request Tracing. The files are not created.
Installation
I'm using IIS 10 on Windows 10. I installed it with the "Turn Windows Features on or off" interface. When I installed, I also checked the box next to World Wide Web Services -> Health and Diagnostics -> Tracing. I did not check the boxes next to any ASP.NET version.
Site Setup and Error
I then installed Application Request Routing 3 (ARR 3), which came with the URL Rewrite module. I have two sites/servers in a server farm for the purposes of blue-green deployment. They are both ASP.NET Core MVC applications. Everything works fine when I browse directly to the sites from my browser. But, for about 10 seconds after stopping one site, the server farm does not switch to the other site and instead returns a 502.3 Error (A connection with the server could not be established). After those 10 seconds, the server farm finally switches to the other site and returns pages correctly. I turn to Failed Request Tracing to hopefully get rid of this 10-second down time.
Failed Request Tracing Config
I have enabled Failed Request Tracing on all sites. I changed the default output directory, and I made sure that both IUSR and IIS_USRS have full access to that directory. I have also added tracing rules to all sites. Each time, I specified "All Content", gave status codes 100-999, selected the "WWW Server" Provider, included the "Rewrite" and "RequestRouting" Areas, and set Verbosity to "Verbose".
The Problem
I have done all this and yet I see no trace logs in the configured output folder. Can anyone tell me why that might be?
