I'm trying to spin up an ELK stack on a CentOS 7 server. I got everything installed correctly (as far as I know). However, when I go to my Kibana Dashboard, It won't let me declare an index pattern. I followed the tutorial at https://www.digitalocean.com/community/tutorials/how-to-install-elasticsearch-logstash-and-kibana-4-on-centos-7
I have absolutely no experience with this, so I'm not sure what logs to post (or how to retrieve them), or how to diagnose the problem. I've been googling like crazy for the last few days, and I'm at my wit's end. I'll appreciate any help you guys can give me. It appears as though my logstash-forwarders aren't sending logs to the main server, but again, I'm not sure how to tell because I'm so new at this.
Looking forward to hearing from you,
