[syslog-ng] Send GELF log messages to Syslog-NG server

[Peter Czanik (pczanik)]

Hi,

That's right: there is no GELF source in syslog-ng. However, you should be able to send logs from Graylog using one of the syslog protocols, and those are pretty well supported by syslog-ng 🙂

While syslog-ng can send logs in GELF format, I don't see anything in
the documentation about it being able to receive (accept) them in this
format.
