For one, I think you were sending your log messages not to an RFC5424 capable source, you need to use the syslog() driver, for example:

source src {
  syslog(transport(udp));
};


There are other transports available (like tcp or tls). The NIL value at the date position seems to be supported, but I am not sure which version added this. I've checked out the current master.

But I think what you are after is the "no-parse" flag.

source src {
  tcp(flags(no-parse));
};

This means that the entire line received is stuffed into the $MSG name-value pair.

Hi All!

The solution is:
Use old RFC3164 message syntax without timestamp:
The UDP message is:
"<prio>procname[procid]: LogMessage"

prio: byte 0-191 (See more information in RFC3164 https://www.ietf.org/rfc/rfc3164.txt)
procname: string (max length 48 character)
procid: number (Max length 128 character)
Full UDP message length 1024 character

Best regards

I see. Then the easiest is probably to not bother with the timestamp on the
sender (arduino) side, and set the keep-timestamp(no) option on the server
side.

Hi!

I write a program on arduino embended system.
This device do not have Real Time Clock.
I sended UDP syslog datagram from this device.

Hi,

The  easiest way to drop the timestamp is on the syslog-ng server side,
where you write the message into a file. There you can use a template,
something like the one below. But why do you want to send a message without
a timestamp?

destination d_file {
    file ("/var/log/messages" template("${MSG}\n") );};

Hi All!

I would like send UDP message to the syslog server without timestamp.

I readed RFC3164 and RFC5424 and syslog-ng-ose-guide-admin.pdf.

The new "RFC 5424 (also called the IETF-syslog protocol): see Section
2.8.2,
IETF-syslog messages (p. 13)" support NIL values "-" in HEADER.

I sended this "<110>1 - hostname procname procid - - Message"

The syslog-ng server logged this:

"Sep 21 19:29:54 h164-19 1: - hostname procname procid - - Message"

Question:
What is wrong in my message string?
The syslog-ng server why do not decode "1" after ">" as version?
Can i send old syslog message (RFC3164) without timestamp?

Best Regards
Istvan Csuti
