Kibana 简明教程

Kibana - Working With Coordinate Map

Kibana 中的坐标地图将显示地理区域,并根据您指定的聚合用圆圈标记区域。

Create Index for Coordinate Map

用于坐标地图的 Bucket 聚合是 geohash 聚合。对于这种聚合类型,您要使用的索引应具有地理点类型字段。地理点是纬度和经度的组合。

我们将使用 Kibana 开发工具创建一个索引,并向其中添加批量数据。我们将添加映射并添加所需的 geo_point 类型。

我们要使用的数据如下所示 −

{"index":{"_id":1}}
{"location": "2.089330000000046,41.47367000000008", "city": "SantCugat"}
{"index":{"_id":2}}
{"location": "2.2947825000000677,41.601800991000076", "city": "Granollers"}
{"index":{"_id":3}}
{"location": "2.1105957495300474,41.5496295760424", "city": "Sabadell"}
{"index":{"_id":4}}
{"location": "2.132605678083895,41.5370461908878", "city": "Barbera"}
{"index":{"_id":5}}
{"location": "2.151270020052683,41.497779918345415", "city": "Cerdanyola"}
{"index":{"_id":6}}
{"location": "2.1364609496220606,41.371303520399344", "city": "Barcelona"}
{"index":{"_id":7}}
{"location": "2.0819450306711165,41.385491966414705", "city": "Sant Just Desvern"}
{"index":{"_id":8}}
{"location": "2.00532082278266,41.542294286427385", "city": "Rubi"}
{"index":{"_id":9}}
{"location": "1.9560805366930398,41.56142635214226", "city": "Viladecavalls"}
{"index":{"_id":10}}
{"location": "2.09205348251486,41.39327140161001", "city": "Esplugas de Llobregat"}

现在,在 Kibana 开发工具中运行以下命令,如下所示 −

PUT /cities
{
   "mappings": {
      "_doc": {
         "properties": {
            "location": {
               "type": "geo_point"
            }
         }
      }
   }
}

POST /cities/_city/_bulk?refresh
{"index":{"_id":1}}
{"location": "2.089330000000046,41.47367000000008", "city": "SantCugat"}
{"index":{"_id":2}}
{"location": "2.2947825000000677,41.601800991000076", "city": "Granollers"}
{"index":{"_id":3}}
{"location": "2.1105957495300474,41.5496295760424", "city": "Sabadell"}
{"index":{"_id":4}}
{"location": "2.132605678083895,41.5370461908878", "city": "Barbera"}
{"index":{"_id":5}}
{"location": "2.151270020052683,41.497779918345415", "city": "Cerdanyola"}
{"index":{"_id":6}}
{"location": "2.1364609496220606,41.371303520399344", "city": "Barcelona"}
{"index":{"_id":7}}
{"location": "2.0819450306711165,41.385491966414705", "city": "Sant Just Desvern"}
{"index":{"_id":8}}
{"location": "2.00532082278266,41.542294286427385", "city": "Rubi"}
{"index":{"_id":9}}
{"location": "1.9560805366930398,41.56142635214226", "city": "Viladecavalls"}
{"index":{"_id":10}}
{"location": "2.09205348251486,41.3s9327140161001", "city": "Esplugas de Llobregat"}

现在,在 Kibana 开发工具中运行以上命令 −

kibana dev tools

上述将创建类型为 _doc 的索引名称城市,字段位置为类型 geo_point。

现在,让我们向索引添加数据:城市 −

kibana index name

我们已完成创建名称为 cities พร้อม数据的索引。现在,让我们使用管理选项卡为城市创建索引模式。

kibana index pattern

此处显示了 cities 索引中字段的详细信息 −

kibana index details

我们可以看到 location 是类型 geo_point。我们现在可以使用它来创建可视化。

Getting Started with Coordinate Maps

转至可视化并选择坐标地图。

coordinate maps

选择索引模式城市,并按如下所示配置聚合指标和桶 −

configure aggregation metric

如果您单击“分析”按钮,则可以看到以下屏幕 −

analyze button

根据经度和纬度,圆圈绘制在地图上,如上所示。
