Thanks. I think will work for what I need to do, but just to be
completely clear, if I understand this correctly, you may only adjust
the appender threshold on a per-appender basis, not per
category/appender pair, so the following WON'T work:

    my $conf =3D q{
    log4perl.logger.mycat =3D DEBUG, Screen1, Screen2
    log4perl.logger.another_cat =3D DEBUG, Screen1, Screen2

    log4perl.appender.Screen1   =3D Log::Log4perl::Appender::Screen
    log4perl.appender.Screen1.layout =3D SimpleLayout
    log4perl.appender.Screen1.Threshold =3D DEBUG

    log4perl.appender.Screen2   =3D Log::Log4perl::Appender::Screen
    log4perl.appender.Screen2.layout =3D SimpleLayout
    log4perl.appender.Screen2.Threshold =3D DEBUG
    };

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

    my $logger =3D get_logger("mycat");
    my $another_logger =3D get_logger("different_cat");

    $logger->debug("both appenders");
    Log::Log4perl->appender_thresholds_adjust(+1, ['Screen1']);

    $logger->debug("one appender");
    $logger->info("both appenders again");
    $another_logger->debug("both appenders"); # Uh oh, goes to only
Screen2=20
=20
