Re: [syslog-ng] syslog-ng has add extra field

25 Mar 2021

      Thanks for your reply, János !

If you can explain me please what does that mean?
...
network(transport(tcp|udp))
or
syslog() or network(transport(tcp|udp) flags(syslog-protocol))
======================================================================

my config:

@version: 3.18
@include "scl.conf"

source s_local {
        internal();
};

source s_network {
        default-network-drivers(
                # NOTE: TLS support
                #
                # the default-network-drivers() source driver opens the TLS
                # enabled ports as well, however without an actual key/cert
                # pair they will not operate and syslog-ng would display a
                # warning at startup.
                #
                #tls(key-file("/path/to/ssl-private-key") cert-file("/path/to/ssl-cert"))
        );
};

destination d_local {
#       file("/var/log/messages");
        file("/var/log/messages-kv_${YEAR}-${MONTH}-${DAY}.log" template("$ISODATE $HOST $(format-welf --scope all-nv-pairs)\n") frac-digits(3));
        file("/var/log/messages_${HOST}.log"
        perm(0644)
        );
};

destination d_logstore {
        file(
           "/var/log/remote/${HOST}/${HOST}_${YEAR}-${MONTH}-${DAY}.log"
        create-dirs(yes)
    );
};

log {
        source(s_local);
        source(s_network);
        destination(d_local);
        destination(d_logstore);
#       destination(d_sorted);
};

Hello Ivan,

Most commonly there may be two main formats of logs that you may encounter.
One is the traditional BSD-style syslog, described in RFC 3164: https://tools.ietf.org/html/rfc3164
The other is the IETF-style log format, described in RFC 5424: https://tools.ietf.org/html/rfc5424

In case of syslog-ng you would have to either use
network(transport(tcp|udp))
or
syslog() or network(transport(tcp|udp) flags(syslog-protocol))
respectively.

The sample logs you included seem to resemble the IETF-style.
What type of source do you have configured in your syslog-ng setup? (Could you please share your config file?)

Best Regards,
János

Hi all!

I think I have a stupid question, but I really dont know how this make.

Situation:
When I send syslog message with timestamp in  format "1Mar 25 2021 16:35:49" everything works great, but when  I send  message with timestamp in format "1Mar 25 2021 16:35:49+03:00", syslog-ng adding two extra fields with timestamp and IP address and due that break down  file naming.

Question:
How can I say to syslog-ng server do not  add extra fields when he  get message with +03:00  in timestamp?

message without +03:00
Mar 25 13:11:57 HUAWEI-CORE-OFFICE-1   <bla bla bal>

mesage with  +03:00
Mar 25 13:46:45 192.168.100.34 Mar 25 2021 16:46:45+03:00 HUAWEI-CORE-OFFICE-1  <bla bla bla>

I will be appreciate for any advice!

P.s sorry for bad english it is not my native language
