I'm sorry to bother you with another question concerning Windows Eventlog forwarding to graylog. Unfortunately I'm not able to figure this out on my own.
nxlog 2.10.2102 (running on Windows Server 2016)
graylog 2.4.6 (running on Debian 9)
I have two nxlog setups. One using syslog and another one using GELF. Both do not work as I would expect.
