Default dynamic mapping template

Elastic Stack Elasticsearch
1

I understand that elasticsearch automatically creates mapping definition when it is not preconfigured.

https://www.elastic.co/guide/en/elasticsearch/reference/master/docs-index_.html#index-creation

For example below field is automatically created when I insert data from logstash.

      "src_ip": {
        "type": "text",
        "fields": {
          "keyword": {
            "type": "keyword",
            "ignore_above": 256
          }
        }
      },

Is there a way to check the default dynamic mapping template?

Logstash register the template to Elasticsearch by this name.

You can see the template using _template API

Hi Ohtani-san.

Thank you for the reply.

Is this still the case when the index name does not match the logstash- ?

I have stored log using filebeat through logstash and index name is filebeat-2016.09.12 and some fields includes multi fields. I did not manually import any json setting packaged inside filebeat.

I use filebeat 1.3.0 -1 and logstash 5.0.0 alpha 5.
