Hello, You need to set keep-alive(no): https://www.syslog-ng.com/technical-documents/doc/syslog-ng-open-source-edit... For example: @version: 3.26 log { source { example-msg-generator(num(1)); }; # destination { network(localhost port(5555) transport(udp) keep-alive(no)); }; destination { syslog(localhost port(5555) transport(udp) keep-alive(no)); }; }; Br, Antal ________________________________ From: syslog-ng <syslog-ng-bounces@lists.balabit.hu> on behalf of Alexandre Santos <alexandre.rosas.santos@gmail.com> Sent: Friday, March 6, 2020 21:02 To: Syslog-ng users' and developers' mailing list <syslog-ng@lists.balabit.hu> Subject: [syslog-ng] restart vs reload CAUTION: This email originated from outside of the organization.

Hi, I am trying to dynamically change the output message format between RFC3164 and RFC5424. root@localhost:~# diff /etc/syslog-ng/syslog-ng.conf /root/syslog-ng.conf.bak 365c365 < network("192.168.122.1" transport("udp") ip-protocol(4) port(514) ---

syslog("192.168.122.1" transport("udp") ip-protocol(4) port(514)

If I use: "/usr/sbin/service syslog-ng restart" it works fine, but if I use "/usr/sbin/syslog-ng-ctl reload", the message format does not change. I am using syslog-ng version 3.19 Any thoughts? Thanks & Regards, Alex
