Hmm there i have the problem. I don't really understand the grokking patterns and the config files from Logstash. So I don't know how I can do that what you want me to do.

So if someone has some hints for me concerning commenting out which parts and test, I'm open to do it.

In Kibana i have the following sentence: unable to fetch mapping. Do you have indices matching the pattern?
