Geoip filter not creating type geo_point but only string type

[vivitare]

Hello,

I'm trying to create a Kibana map with coordinates points from apache log using the plugin geoip.
The problem is no geo_point type are created in Elasticsearch. However, apache log are correctly parsed by filter in the logstash configuration. All geoip data appear in string type. So i can't select this index pattern in Kibana Maps

This is my logstash 02-apache-log.conf configuration file :

input {
    beats {
        port => "5044"
    }
}
filter {
    grok {
        match => { "message" => "%{COMBINEDAPACHELOG}" }
    }
    geoip {
        source => "clientip"
        target => "geoip"
    }
}
output {
    elasticsearch {
        hosts => localhost
        index => "%{[@metadata][beat]}-%{[@metadata][version]}-%{+YYYY.MM.dd}"
    }
    stdout { codec => rubydebug }
}

geoip data remonted in stdout :

   "geoip" => {
   "country_name" => "United Kingdom",
       "latitude" => 53.8247,
      "longitude" => -2.2342,
      "city_name" => "Burnley",
  "country_code3" => "GB",
 "continent_code" => "EU",
    "region_name" => "Lancashire",
    "region_code" => "LAN",
  "country_code2" => "GB",
             "ip" => "86.1.76.62",
    "postal_code" => "BB10",
       "timezone" => "Europe/London",
       "location" => {
     "lon" => -2.2342,
     "lat" => 53.8247
 }

Apache log example :

86.1.76.62 - - [04/Jan/2015:05:30:37 +0000] \"GET /style2.css HTTP/1.1\" 200 4877 \"http://www.semicomplete.com/projects/xdotool/\" \"Mozilla/5.0 (X11; Linux x86_64; rv:24.0) Gecko/20140205 Firefox/24.0 Iceweasel/24.3.0\"

Logstash version : 7.7.0

@vivitare

index => "%{[@metadata][beat]}-%{[@metadata][version]}-%{+YYYY.MM.dd}"

Do you have an index template that tells elasticsearch that geoip contains a geo_point for that index name? The default template, which does so, only applies to indexes whose names start with logstash-

Thks for answer.
I tried to change index name by logstash-%{+YYYY.MM.dd} and it's working. Type geo_point is created in Elasticsearch and i can use the data in Kibana maps.
