Hi. you must use fluent-plugin-elasticsearch and write own template with mapping field: example_template:

{
  "index_patterns": ["logstash-*", "otherpattern-*"],
  "mappings": {
    "properties": {
        "size":{ "type": "integer"},
        "coordinates":{ "type": "geo_point"},
        "remote":{ "type": "ip"},
        "code":{ "type": "short"}
    }
  }
}

and configure fluent in elasticsearch section like: ... template_file /fluentd/etc/example_template template_name example_template template_overwrite true max_retry_putting_template 15 ...
