Which version of Graylog are you using? The screenshot from your docu on github seems to be 2.x?
Hi, There is a problem of compatibility for the version 5.0.5 of graylog. Do you know how to adapt fort this version ?
I don’t think that will be easily possible. You may read the JSON files to get an idea, what was supposed to happen and reconstruct that in your Graylog.
