I found these topics:
https://community.openhab.org/t/logging-to-filebeat-elasticsearch-kibana/79544
But I got error when I set layout.type to ‘JSONLayout’.
Great!
Well… if you don’t share the error message how are we supposed to help you 
Did you figure this out?
As I am maybe facing the same issue.
The error message is:
