Kibana uses index patterns to discover Elasticsearch indexes. You need to create an index pattern in Kibana. https://www.elastic.co/guide/en/kibana/current/index-patterns.html

thank you
the index pattren should i created before or after loding data
because i can't create the index before loading data to elasticsearch
the problem is in the load of data to elasticsearch with logstash

Does the index exist in Elasticsearch? Use _cat/indices to find out.
