[Catalyst] How to enhance Log4Perl log-files about the loggend in user ($c->user->id)?

[Jon Schutz]

Somewhere early on on the request cycle do

Log::Log4perl::MDC->put( 'user' => $user );

then insert it into your log messages via your Log4perl configuration
such as:

log4perl.appender.Logfile.layout.ConversionPattern: "%d %-5p %c -
USER:%X{user} - %m%n"
