If I understand your problem, you want a child process to send its STDOUT and STDERR output through a Log4Perl object that is located in the parent process.

If so, then the parent has to process the child's output and pass it to the logging object. Here's a simple way to do this for just STDOUT: 

my $pid = open(CHILD, "-|", 'child', @child_args)
if ($pid) {
  while (<CHILD>) { $logger->($_) }
}
close(CHILD);

If it's okay to merge STDOUT and STDERR, you can do something like this: 
if (my $pid = open(CHILD, "-|")) {
  while (<CHILD>) { $logger->($_); }
  close(CHILD);
} else {
  open(STDERR, '>&STDOUT');
  exec('child', @child_args) || die "exec failed";
}

When Proc::Daemon runs, it somehow takes over STDOUT and STDERR so I don't see the messages.
All Proc::Daemon is doing is redirecting STDOUT and STDERR to /dev/null.
