Chart Links

Enable data association through chart-related links, allowing for navigation from the current chart to a target page while passing data information. The system provides the following template variables:

Variable Types

Supports 4 types of template variables:

  • Time variables
  • Label 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", then 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 top right corner of the chart; when locked, it is the start time of the locked period
#{endTime} When time is not locked, it is the end time of the time widget in the top right corner of the chart; when locked, it is the end time of the locked period
Note

During actual queries, you can use the time variables #{startTime} and #{endTime} as placeholders along with view variables. The system will replace them based on globally set variable values.

Label Variables

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

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

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

    View Variables

    Variable Description
    #{V} A 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:
  • 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 by any variable name.
    Assume the current dashboard's view variable is version=V1.7.0

    Then:
  • 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} Data value variable returned by the current chart query. For example, if querying M::cpu:(AVG(load5s)) results in AVG(load5s)=a

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

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

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

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

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

    Then:
  • Value variable &query=Size:#{Value.Size} is equivalent to &query=Size:1773
    		•
    Table chart #{Value.column_name} Selected column value variable from the current chart, where name can be replaced by any column variable name. For example, if querying L::RE(.*):(COUNT(*)) { index = default }
    Query result: count(*)=40813

    Then:
  • Value variable &query=#{Value.count(*)} is equivalent to &query=count(*):40813
    		•
    Rectangular treemap
    Hexbin chart
    World map
    China map    		 #{Value.metric_name} Selected query data value variable from the current chart, where name can be replaced by any column variable name. For example, if querying L::RE(.*):(MAX(response_time)) { index = default } BY country
    Query result: max(response_time)=16692

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