> Hi,
> According to GELF specification, when using TCP protocol a '\0' null byte must be appended at the end of message as frame delimiter.
> http://docs.graylog.org/en/latest/pages/gelf.html#gelf
> Using below config messages do not appear in Graylog.
> Everything is fine when using UDP, or when using GELF appender (https://github.com/graylog-labs/log4j2-gelf), so logging config itself is ok.
> I can see the packets in Wireshark, only Graylog ignores them.
> {code:xml}
> <Socket name="SocketTcp" protocol="TCP" host="dit17mpc029.dorsum.intra" port="12201" ignoreExceptions="false">
> <GelfLayout host="jenkins-sock-tcp" compressionType="OFF"/>
> </Socket>
> {code}
