Hi,

this is now more a MooseX::Log::Log4perl related question. When you look at the perldoc of that package IMHO anything is said. You have to initialize the Log::Log4perl singleton before logging the first time. Example is given in the perldoc.

Init like

my $log4perl_conf = q(
log4perl.logger=DEBUG, STRINGCOLLECTOR
log4perl.appender.STRINGCOLLECTOR = Log::Log4perl::Appender::String
log4perl.appender.STRINGCOLLECTOR.layout = Log::Log4perl::Layout::Patt
+ernLayout
log4perl.appender.STRINGCOLLECTOR.layout.ConversionPattern = %p:%d{ISO
+8601}:myscript: %m%n
);
Log::Log4perl->init( \$log4perl_conf );

before first usage.

UPDATE: As the doc says: You can get the logger instance with $self->logger. So later you should get the collected output with

my $appender = $self->logger->appender_by_name('STRINGCOLLECTOR');
my $string = '';
if($appender) {
    $string = $appender->string();
}
