Just upgraded a node from 6.8.1 to 7.2.0 and I'm getting the error message right after I start with journalctl that states
Jul 11 14:10:30 dch1092ql5app kibana: FATAL Error: [elasticsearch.url]: definition for this key is missing
After reading the error message it seemed like a pretty easy fix, just make sure that elasticsearch.url has been filled in. Yet when I add our elasticsearch url in Kibana starts and then stops with the same error message.
# The URL of the Elasticsearch instance to use for all your queries. #elasticsearch.url: "http://localhost:9200" #elasticsearch.url: "https://abc.gov:9200" elasticsearch.url: "http://abc.gov:9200"
