Hi. Im trying to change the thresold on an appender, but without success. Why do I want to do this ? - it would be in response to a '-debug' option provided to the script ( not shown for clarity ) Minimal case example of the issue is shown below. Suggestions very gladly welcomed Thank you. 

#!/usr/bin/perl

use strict;
use warnings;

use Log::Log4perl;

my $log4p_conf = q(

    log4perl.rootLogger=DEBUG, SCREEN

    log4perl.appender.SCREEN=Log::Log4perl::Appender::Screen
    log4perl.appender.SCREEN.layout=SimpleLayout
    log4perl.appender.SCREEN.Threshold=INFO

);

Log::Log4perl->init(\$log4p_conf);

my $log = Log::Log4perl->get_logger("");

# This appears to have no effect :
Log::Log4perl->appender_by_name('SCREEN')->threshold('DEBUG');

$log->fatal("fatal msg");
$log->error("error msg");
$log->warn("warn msg");
$log->info("info msg");
$log->debug("debug msg");
$log->trace("trace msg");
