I just updated my stack from 6.7.0 -> 6.8.0 -> 7.4.0. Everything seems find EXCEPT logstash is putting all the events into an index called "logstash". I used to date-stamp the index, like "logstash-2019-10-24". I cannot figure out why, I've been pulling my hair out for 24 hours on this now.
I run just a single node in a docker container. All my config is here https://github.com/kenwdelong/elk-docker/tree/ELK-7.4.0, I didn't change anything from 6.7.0.
Any help would be appreciated!!!
