Chart Linking

By associating chart links, data linkage can be achieved, supporting navigation from the current chart to the target page while passing data information. The system provides the following template variables:

Variable Types

Supports 4 types of template variables:

Time Variables

Tag Variables

View Variables

Value Variables

Time Variables

Variable
 Description
#{TR} The time range of the current chart query. For example, if the query time is Last 1 hour, the template variable &time=#{TR} is equivalent to &time=1h.
#{timestamp.start} The start time of the selected data point in the current chart query.
#{timestamp.end} The end time of the selected data point in the current chart query.
#{startTime} When time is not locked, it is the start time of the time widget in the upper right corner of the chart. When locked, it is the start time of the locked time period.
#{endTime} When time is not locked, it is the end time of the time widget in the upper right corner of the chart. When locked, it is the end time of the locked time period.
Note

During actual query execution, time variables #{startTime} and #{endTime}, as well as view variables, can be used as placeholders. The system will replace them based on the globally set variable values.

Tag Variables

Variable Description
#{T} The collection of all grouped tags for the current chart query. For example, if the query is:
M::'datakit':(LAST('cpu_usage')) BY 'host','os'
The query result is: host=abc, os=linux

Then:
  • The template variable: &query=#{T} is equivalent to &query=host:abc os:linux
    		•
    #{T.name} The value of a specific tag. For example, if the query is:
    M::'datakit':(LAST('cpu_usage')) BY 'host', 'os'
    The query result is: host=abc, os=linux

    Then:
  • The template variable #{T.host} = abc
    &query=hostname:#{T.host} is equivalent to &query=hostname:abc
    		•

    View Variables

    Variable Description
    #{V} The collection of all view variables in the current dashboard. For example, if the view variables are:
    version=V1.7.0 and region=cn-hangzhou

    Then:
  • The template variable &query=#{V} is equivalent to &query=version:V1.7.0 region:cn-hangzhou
    		•
    #{V.name} The value of a specific view variable in the current dashboard, where 'name' can be replaced with any variable name.
    Assume the current dashboard's view variable is version=V1.7.0

    Then:
  • The template variable #{V.version} = V1.7.0
  • &query=version:#{V.version} is equivalent to &query=version:V1.7.0
    		•

    Value Variables

    Chart Type
    Variable
    		 Description
    Time Series Chart
    Summary Chart
    Pie Chart
    Bar Chart
    Top List
    Dashboard
    Funnel Chart    		 #{Value} The data value variable returned by the current chart query. For example, if the query M::cpu:(AVG(load5s)) returns: AVG(load5s)=a

    Then:
  • The value variable: &query=#{Value} is equivalent to &query=AVG(load5s):a
    		•
    Scatter Plot #{Value.X} The X-axis data value variable returned by the current chart query. Assume the current chart query is:
    M::cpu:(AVG(load5s))
    The query result is: X:AVG(load5s)=abc

    Then:
  • The value variable: &query=#{Value.X} is equivalent to &query=X:abc
    		•
    #{Value.Y} The Y-axis data value variable returned by the current chart query. For example, if the query M::backuplog:(AVG(lru_add_cache_success_count))
    returns: Y:AVG(lru_add_cache_success_count)=dca

    Then:
  • The value variable &query=Y:#{Value.Y} is equivalent to &query=Y:dca
    		•
    Bubble Chart #{Value.X} The X-axis data value variable returned by the current chart query. For example, if the query T::RE(.*):(FIRST(duration)) BY service
    returns: X:first(duration)=98

    Then:
  • The value variable: &query=X:#{Value.X} is equivalent to &query=X:98
    		•
    #{Value.Y} The Y-axis data value variable returned by the current chart query. For example, if the query T::RE(.*):(LAST(duration)) BY service
    returns: Y:last(duration)=8500

    Then:
  • The value variable &query=Y:#{Value.Y} is equivalent to &query=Y:8500
    		•
    #{Value.Size} The Size data value variable returned by the current chart query. For example, if the query T::RE(.*):(MAX(duration)) BY service
    returns: Size:Max(duration)=1773

    Then:
  • The value variable &query=Size:#{Value.Size} is equivalent to &query=Size:1773
    		•
    Table Chart #{Value.column_name} The column value variable selected in the current chart, where name can be replaced with any column variable name. For example, if the query L::RE(.*):(COUNT(*)) { index = default }
    returns: count(*)=40813

    Then:
  • The value variable&query=#{Value.count(*)} is equivalent to &query=count(*):40813
    		•
    Treemap
    Hexbin Map
    World Map
    China Map    		 #{Value.metric_name} The query data value variable selected in the current chart, where name can be replaced with any column variable name. For example, if the query L::RE(.*):(MAX(response_time)) { index = default } BY country
    returns: max(response_time)=16692

    Then:
  • The value variable&query=#{Value.max(response_time)} is equivalent to &query=max(response_time):16692
    		•
