$SIG{__DIE__} = sub { $log->trace(emergency => @_) };
    

By default the backtrace is logged as level "debug".

    # would log with the level debug
    $log->trace('who called who');
    

If you want to log with another level then you can pass the level as first argument:

    $log->trace(info => $message);
    

    my %hash = (foo => 1, bar => 2);
    $log->dump(\%hash);
    

If you want to log with another level then you can pass the level as first argument:

    $log->dump($level => \%hash);
    

    $log->die('an emergency error here');
    

If you want to log with another level, then you can pass the level as first argument:

    $log->die(fatal => 'an emergency error here');
    

    $log->log(info => 'an info message');
    

Is the same like

    $log->info('an info message');
    

and

    $log->log('an info message');
    

If you log without a level then the default level is "info".
