The failed request tracing feature assists you in troubleshooting issues
with your websites by making IIS failed request files available in the
Plesk interface. The failed request files contain information such as
the requested URL, relevant application pool name, the HTTP status code,
and more.
To view a list of all failed requests files created so far, go to the
Websites and Domains tab > Failed Requests Tracing. You can
click any of the failed requests files to view their contents; you can
also download one or more files packed into a ZIP archive, or remove the
files that are no longer necessary. You can start a new trace by
specifying one or more HTTP status codes and the IIS component or
components for which failed request files will be created. Once a trace
is started, you can change these settings at any time.
