How to pick an appender selectively in Log::Log4perl

[hellosarathy]

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?

Thanks.

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
        
    );
