We were trying to put a visualization directly in Kibana/ElasticSearch using "/.kibana/visualization/" API. We are currently using 6.2.3 version of elasticsearch. After creating the visualization we got the following response:
Here, we got index name as a hex value. Now when we want to retrieve the visualization , we donot know the index name we need to query. Can you please elaborate what does this hex value signify and how is this mapping maintained.
