在Ubuntu 14.04上的ELK 6.3版本中将经纬度转换为地理数据类型

Question

我们正在尝试使用ELK 6.3版中的.conf文件和.json（模板文件）将数据推送到elasticsearch中。最初，我们使用模板文件将数据成功推送到ELK 4.x版本，并且能够在地图上渲染点。但是在新版本中，无论是否使用模板文件，lat和lon在Kibana中仅被视为数字。

我们如何推lat，lon以使其具有geopoint类型？我们正在尝试使用logstash配置文件推送数据。

这是我们的.conf文件：

[input
{
    file
        {
        path => "/home/ubuntu/file.csv"
        start_position => "beginning"
        }
}
filter {
    csv {
        separator => ","
        columns => \[
          "CASCADE",
          "Accessibility",
          "Sustainability",
          "CONNECTION_FAIL_per",
          "RRC_CONNECTION_ATTEMPT",     
               "eCSFB_to_CDMA1XRTT_Exe_Succ_Count",
          "eCSFB_Preparation_Success_Rate",
          "eCSFB_Overall_Success_Rate",
          "CSFB_Attempts",
        "Total_PUCCH_PRB_UL_per",
          "lat",
          "lon"


        \]
    }

    mutate { convert => {"lat" => "float"} }
    mutate { convert => {"lon" => "float"} }
    mutate { rename => {"lat" => "\[location\]\[lat\]"} }
    mutate { rename => {"lon" => "\[location\]\[lon\]"} }

}

    elasticsearch {

        hosts => "localhost:9200"
        index => "new"

    }
    stdout {}
}

        }
      } \],

            "lon" : { "type" : "float" }
          }
        },
  "location" : { "type": "geo_point" }
      }
    }
  }
}]

请让我们知道如何转换为地理点
