[syslog-ng] keep_hostname (yes); and source file

[Steven Blatchford]

Hello,

I have a file, /srv/http/foo/var/log/system.log that I would like sent
to our central log.  This config was not working:

    @version: 3.0
    #
    # /etc/syslog-ng.conf
    #

    options {
      stats_freq (0);
      flush_lines (0);
      time_reopen (10);
      log_fifo_size (1000);
      long_hostnames(off);
      use_dns (no);
      use_fqdn (no);
      create_dirs (no);
      keep_hostname (yes);
      perm(0640);
      group("log");
    };

    source s_foo { file("/srv/http/foo/var/log/system.log"); };

    log { source(s_foo); destination(d_net); };

    destination d_net { udp("host.org"); };

It does work if I comment out 'keep_hostname (yes);'.  Can someone
explain to me why this is?
