missing IP information at the message part

1 Jan 2012

      I have syslog-ng and logzilla  2.9.9g installed on a Debian squeeze
machine. I can see the logs at the web interface. I configured
syslog-ng to collect apache error and access logs. The problem is that
i don't see IP information at the message part, on web interface.

For ex, one of the machine that is sending apache logs is "www"
machine. The syslog-ng configuration is as below:

# All messages send to a remote site
#
#log { source(s_src); destination(d_net); };
#manual edit
options { log_msg_size(8192); };
#######
# sources #
#######

source s_apache_access {
                # unix-stream("/var/log/httpd/apache_log.socket"
                # max-connections(512)
                # keep-alive(yes));
                file ("/var/log/apache2/access.log"
                     flags(no-parse));
};

source s_apache_error {
                # unix-stream("/var/log/httpd/apache_log.socket"
                # max-connections(512)
                # keep-alive(yes));
                file ("/var/log/apache2/error.log"
                     flags(no-parse));
};

                            file("/var/log/apache2/custom_error.log");

                             tls(ca_dir("/etc/syslog-ng/etc/ca.d")
                             key_file("/etc/syslog-ng/etc/key.d/debian4key.pem")

cert_file("/etc/syslog-ng/etc/cert.d/debian4cert.pem")));
};

log {
     source(s_apache_error);
#     filter(f_apache_access);
     destination(d_apache_tls);
};

and

# tail -n1 /var/log/apache2/access.log

www:/home/oguz#

For the www machine i don't see the 78.185.240.170 information at the
web ui, but the rest of the line starting with --

Thogh another machine, "reverse", is sending apache logs with and
additional field and i can see its log at the web ui without any
missing information.

The reverse has the same configuration except from the key information.

# tail -n1 /var/log/apache2/other_vhosts_access.log
www.beeseurope.eu:80 178.154.160.29 - - [01/Jan/2012:13:36:46 +0200]

"Mozilla/5.0 (compatible; YandexBot/3.0; +http://yandex.com/bots)"

At the web interface, I can see the IP information also at the message part.

My syslog-ng configuration at the server is as below:

options {
       long_hostnames(off);
       # doesn't actually help on Solaris, log(3) truncates at 1024 chars
       log_msg_size(8192);
       # buffer just a little for performance
       flush_lines(16384);
       # memory is cheap, buffer messages unable to write (like to loghost)
       log_fifo_size(16384);
       # Hosts we don't want syslog from
       #bad_hostname("^(ctld.|cmd|tmd|last)$");
       # The time to wait before a dead connection is reestablished (seconds)
       time_reopen(10);
       #Use DNS so that our good names are used, not hostnames
       use_dns(yes);
       dns_cache(yes);
       #Use the whole DNS name
       use_fqdn(yes);
       keep_hostname(yes);
       chain_hostnames(no);
       #Read permission for everyone
       perm(0644);
       # The default action of syslog-ng 1.6.0 is to log a STATS line
       # to the file every 10 minutes.  That's pretty ugly after a while.
       # Change it to every 12 hours so you get a nice daily update of
       # # how many messages syslog-ng missed (0).
       # stats(43200);
        log_msg_size(8192);
   };

source s_apache {
                             tcp(ip(0.0.0.0) port(6514)
                             tls(

   destination(d_logzilla);
};

log {
   source(s_apache);
   filter(f_apache_error);
   destination(d_apache_test_error);
};

log {
   source(s_apache);
   filter(f_apache_access);
   destination(d_apache_test_access);
};

Any ides about how i can fix the missing IP information at the web ui
of logzilla?
