use Log::Log4perl::Appender::Screen; my $app = Log::Log4perl::Appender::Screen->new( autoflush => 1, stderr => 0, utf8 => 1, ); $file->log(message => "Log me\n");
The constructor "new()" takes an optional parameter "stderr":
# All messages/levels to STDERR my $app = Log::Log4perl::Appender::Screen->new( stderr => 1, ); # Only ERROR and FATAL to STDERR (case-sensitive) my $app = Log::Log4perl::Appender::Screen->new( stderr => { ERROR => 1, FATAL => 1}, );
Design and implementation of this module has been greatly inspired by Dave Rolsky's "Log::Dispatch" appender framework.
To enable printing wide utf8 characters, set the utf8 option to a true value:
my $app = Log::Log4perl::Appender::Screen->new( stderr => 1, utf8 => 1, );
This will issue the necessary binmode command to the selected output channel (stderr/stdout).
To enable autoflush, set the "autoflush" option to a true value:
my $app = Log::Log4perl::Appender::Screen->new( autoflush => 1, );
This will issue the necessary autoflush command to the selected output channel (stderr/stdout).
This is required in containers, especially when the log volume is low, to not buffer the log messages and cause a significant delay.
