How to pick an appender selectively in Log::Log4perl

hellosarathy has asked for the wisdom of the Perl Monks concerning the following question:

Dear Monks,

I have a Log::Log4perl logger configured which writes to STDOUT, SYSLOG and Logfile, like:

my %loggerConfig = ( "log4perl.category.default_logger" => "INFO, Stdout, SYSLOG, Logfile",
which writes to STDOUT, SYSLOG and Logfile. Few messages I need to write ONLY to the log file and NOT to syslog and STDOUT. How can this be done?

    Create a separate category that only writes to Logfile
    my %loggerConfig = ( "log4perl.category.default_logger" => "INFO, Stdout, SYSLOG, Logfile +", "log4perl.category.file.only" => "INFO, Logfile", );
    Then to use it:
    my $log = Log::Log4perl->get_logger("file.only"); $log->info('whatever');

    You can select what you want. I would do it like this.
    my $log_conf = qq( log4perl.rootLogger = DEBUG, LOG log4perl.appender.LOG = Log::Log4perl::Appender: +:File log4perl.appender.LOG.filename = $ref->{config}->{Log} log4perl.appender.LOG.mode = append log4perl.appender.LOG.layout = Log::Log4perl::Layout::P +atternLayout log4perl.appender.LOG.layout.ConversionPattern = %d %p %m %n );
