I deploy kibana for my private openstack cloud and I am seeing licensing issues with the API on the open source version.
{"level":"ERROR","loggerName":"logstash.outputs.elasticsearch","timeMillis":1629936010246,"thread":"Ruby-0-Thread-9: :1","logEvent":{"message":"Unable to get license information","url":"http://10.0.200.21:9200/","exception":{"metaClass":{"metaClass":{"exception":"LogStash::Outputs::ElasticSearch::HttpClient::Pool::BadResponseCodeError","message":"Got response code '400' contacting Elasticsearch at URL 'http://10.0.200.21:9200/_license'"}}}}}
{"level":"ERROR","loggerName":"logstash.outputs.elasticsearch","timeMillis":1629936010246,"thread":"Ruby-0-Thread-9: :1","logEvent":{"message":"Could not connect to a compatible version of Elasticsearch","url":"http://10.0.200.21:9200/"}}
Here is my elasticsearch version:
{
"name" : "10.0.200.20",
"cluster_name" : "kolla_logging",
"cluster_uuid" : "MAinUYsrS-evlWA35ro3dg",
"version" : {
"number" : "7.10.2",
"build_flavor" : "oss",
"build_type" : "rpm",
"build_hash" : "747e1cc71def077253878a59143c1f785afa92b9",
"build_date" : "2021-01-13T00:42:12.435326Z",
"build_snapshot" : false,
"lucene_version" : "8.7.0",
"minimum_wire_compatibility_version" : "6.8.0",
"minimum_index_compatibility_version" : "6.0.0-beta1"
},
"tagline" : "You Know, for Search"
}
How to reproduce:
OS : Centos 8.3.2011

Kolla version : Wallaby
From IRC: I had monasca enabled which was mentioned uses the ELK stack, it was suggested to disable monasca and use the EFK stack.
Not exactly related to Kibana, it's Logstash vs. Elasticsearch versions mismatch.
