> [@Jenni](#): > > Just to check the most obvious solution: Did you define multiple pipelines in pipelines.yml or just create another file? Logstash concanates all conf files in conf.d to one big main pipeline if you don't configure multiple pipelines. Oh wow, I wasn't aware of that! so you mean it takes all the files and make a huge pipeline out of them? Okay, that's probably it. I used to have logstash on Windows a year ago, then left it and now I created a logstash server on linux. I remembered that I needed to configure pipline yaml but it just worked, so I never go to do it. this is probably the answer! --- _[View the full topic](https://discuss.elastic.co/t/logstash-mixing-up-two-configuration-files/238540)._
