[log4perl-devel] Different log layout per level ?
Hello, I recently started toying with log4perl, and incorporated it in an application. I need the capability to define a log layout for WARN messages that is a lot more user-friendly/readable than the others. After reading the documentation at: http://log4perl.sourceforge.net/releases/Log-Log4perl/docs/html/Log/Log4perl.html#1d6b5 and the tutorial, I haven't seen a way to define such different layouts per level. Did I just miss it ? Is this possible using log4perl ?

Re: [log4perl-devel] Different log layout per level ?
It's possible, but it's probably less than straightforward. Each appender has exactly one layout, so what you'll need to do is create two appenders, and use some combination of thresholds and filters so that one appender only logs WARN messages and the other appender logs everything else.

Exactly, something along these lines:
use Log::Log4perl qw(:easy);
my $conf = q{
log4perl.logger = DEBUG, AppWarn, AppRest
# Filter to match level WARN
log4perl.filter.MatchWarn = Log::Log4perl::Filter::LevelMatch
log4perl.filter.MatchWarn.LevelToMatch = WARN
log4perl.filter.MatchWarn.AcceptOnMatch = true
# Filter to match everything but WARN
log4perl.filter.MatchRest = Log::Log4perl::Filter::LevelMatch
log4perl.filter.MatchRest.LevelToMatch = WARN
log4perl.filter.MatchRest.AcceptOnMatch = false
# Elaborate layout for WARN messages
log4perl.appender.AppRest = Log::Log4perl::Appender::Screen
log4perl.appender.AppRest.layout = PatternLayout
log4perl.appender.AppRest.layout.ConversionPattern = %F-%L %m%n
log4perl.appender.AppRest.Filter = MatchWarn
# Normal layout for the rest
log4perl.appender.AppWarn = Log::Log4perl::Appender::Screen
log4perl.appender.AppWarn.layout = PatternLayout
log4perl.appender.AppWarn.layout.ConversionPattern: %m%n
log4perl.appender.AppWarn.Filter = MatchRest
};
Log::Log4perl->init(\$conf);
DEBUG "debug message";
WARN "warn message";
ERROR "error message";
will print
debug message
./t-38 warn message
error message
