Is it possible to define the index.routing.allocation.require.box\_type in the graylog-internal template? Changes to the template are not holding so each new indice has to be updated manually.

Referenced from the the Elasticsearch hot warm architecture for ES version 2.x.

This should be possible with a custom index template: [http://docs.graylog.org/en/2.2/pages/configuration/elasticsearch.html#custom-index-mappings](http://docs.graylog.org/en/2.2/pages/configuration/elasticsearch.html#custom-index-mappings)

Thanks - based on that link, would this be the correct graylog-custom-mapping.json?

```json
{
  "template": "graylog_*",
  "mappings" : {
    "settings" : {
      "properties" : {
        "index": {
          "routing": {
            "allocation": {
              "require": {
                "box_type": "hot"
              }
            }
          }
        }
      }
    }
  }
}

```

No. Index settings must not be listed within the `mappings` dictionary.

See [Index Templates | Elasticsearch Guide [2.4] | Elastic](https://www.elastic.co/guide/en/elasticsearch/reference/2.4/indices-templates.html) for details.
