You can add color blocks and marks to a map to display geographic data. Log Service provides three kinds of maps: Map of China, World Map, and AMap. Among them, AMap offers the scatter chart and heat map. You can use specific functions in query and analysis statements to display analysis results on different maps.

Components

  • Map canvas
  • Color block

Properties

Configuration item Description
Location information The location information recorded in logs. The dimension varies with the map as follows:
  • Provinces (Map of China)
  • Country (World Map)
  • Longitude/Latitude (AMap)
Value Column The data volume of the location information.

Procedure

  1. On the search page of a Logstore, enter a query and analysis statement in the search box, set the time range, and then click Search & Analysis.
    • Map of China: Use the ip_to_province function.
    • World Map: Use the ip_to_country function.
    • AMap: Use the ip_to_geo function.
  2. Click to select the map.
  3. Configure the properties of the map.

Scenarios

Map of China

You can use the ip_to_province function to generate a map of China.

  • SQL statement: 
* | select  ip_to_province(remote_addr) as address, count(1) as count group by address order by count desc limit 10
  • Dataset:
    address count
    Guangdong 163
    Zhejiang 110
    Fujian 107
    Beijing 89
    Chongqing 28
    Heilongjiang 19
  • Select address for Provinces and count for Value Column.

World map

You can use the ip_to_country function to generate a world map.

  • SQL statement:
    * | select  ip_to_country(remote_addr) as address, count(1) as count group by address order by count desc limit 10
  • Dataset:
    address count
    China 8354
    United States 142
  • Select address for Country and count for Value Column.

AMap

You can use the ip_to_geo function to generate an AMap. The address column in the dataset contains the latitude and longitude in sequence, which are separated with a comma (,). If the longitude and latitude are separated in the lng column and the lat column, you can use the concat('lat', ',', lng') function to merge the two columns.

  • SQL statement:
    * | select  ip_to_geo(remote_addr) as address, count(1) as count group by address order by count desc limit 10
  • Dataset:
    address count
    39.9289,116.388 771
    39.1422,117.177 724
    29.5628,106.553 651
    30.2936,120.161420 577
    26.0614,119.306 545
    34.2583,108.929 486
  • Select address for Longitude/Latitude and count for Value Column.

    The scatter chart is used by default. If data points are densely distributed on the map, you can switch to the heat map.
