So I have set up Kibana (v5.2.2) with Logstash (v5.2.2) and Elasticsearch (v5.2.2) on Ubuntu. But currently it works up until the discovery page. On the discovery page it recognises my fields set in the config file but is treating them as "unknown".
You should probably be indexing your data somewhere besides .kibana -- that's a system index that's used as a place for storing Kibana saved objects, but for the data you plan to query you should use a different index with its own index pattern.
I'm guessing that's the root of the issue, but it's also been awhile since I used 5.2, so feel free to reply if you're still running into problems and I'll see if there's anything I can do to help!
