IP Adress and field "source" filled with "unknwn"

How can i get the source client IP in a Log Message field?
The field source in everywhere “unknown”, only field “filebeat_host_name” has the hostname.

I use the newest versions of sidecar (1.0.1), filebeat and graylog (3.0.2).

Thank you!

Search a bit more. I faced the same today. It’s only 5 minutes.

Ok but what about the ip Address?

graylog stores the client IP address (from the incoming package) in gl2_remote_ip field.
If you want in another field, you can modify it with pipelines, or modify the beats config to store in another field
