URL templatingedit

This functionality is in beta and is subject to change. The design and code is less mature than official GA features and is being provided as-is with no warranties. Beta features are not subject to the support SLA of official GA features.

The URL template input uses Handlebars — a simple templating language. Handlebars templates look like regular text with embedded Handlebars expressions.

https://github.com/elastic/kibana/issues?q={{event.value}}

A Handlebars expression is a {{, some contents, followed by a }}. When the drilldown is executed, these expressions are replaced by values from the dashboard and interaction context.

In addition to built-in Handlebars helpers, you can use custom helpers.

Refer to Handlebars documentation to learn about advanced use cases.

Custom helper Use case

json

Serialize variables in JSON format.

Example:

{{json event}}
{{json event.key event.value}}
{{json filters=context.panel.filters}}

rison

Serialize variables in rison format. Rison is a common format for Kibana apps for storing state in the URL.

Example:

{{rison event}}
{{rison event.key event.value}}
{{rison filters=context.panel.filters}}

date

Format dates. Supports relative dates expressions (for example, "now-15d"). Refer to the moment docs for different formatting options.

Example:

{{date event.from “YYYY MM DD”}}
{{date “now-15”}}

formatNumber

Format numbers. Numbers can be formatted to look like currency, percentages, times or numbers with decimal places, thousands, and abbreviations. Refer to the numeral.js for different formatting options.

Example:

{{formatNumber event.value "0.0"}}

lowercase

Converts a string to lower case.

Example:

{{lowercase event.value}}

uppercase

Converts a string to upper case.

Example:

{{uppercase event.value}}

trim

Removes leading and trailing spaces from a string.

Example:

{{trim event.value}}

trimLeft

Removes leading spaces from a string.

Example:

{{trimLeft event.value}}

trimRight

Removes trailing spaces from a string.

Example:

{{trimRight event.value}}

mid

Extracts a substring from a string by start position and number of characters to extract.

Example:

{{mid event.value 3 5}} - extracts five characters starting from a third character.

left

Extracts a number of characters from a string (starting from left).

Example:

{{left event.value 3}}

right

Extracts a number of characters from a string (starting from right).

Example:

{{right event.value 3}}

concat

Concatenates two or more strings.

Example:

{{concat event.value "," event.key}}

replace

Replaces all substrings within a string.

Example:

{{replace event.value "stringToReplace" "stringToReplaceWith"}}

split

Splits a string using a provided splitter.

Example:

{{split event.value ","}}

encodeURIComponent

Escapes string using built in encodeURIComponent function.

encodeURIQuery

Escapes string using built in encodeURIComponent function, while keeping "@", ":", "$", ",", and ";" characters as is.

URL template variablesedit

The URL drilldown template has three sources for variables:

  • Global static variables that don’t change depending on the place where the URL drilldown is used or which user interaction executed the drilldown. For example: {{kibanaUrl}}.
  • Context variables that change depending on where the drilldown is created and used. These variables are extracted from a context of a panel on a dashboard. For example, {{context.panel.filters}} gives access to filters that applied to the current panel.
  • Event variables that depend on the trigger context. These variables are dynamically extracted from the interaction context when the drilldown is executed.

To ensure that the configured URL drilldown works as expected with your data, you have to save the dashboard and test in the panel. You can access the full list of variables available for the current panel and selected trigger by clicking Add variable in the top-right corner of a URL template input.

Variables referenceedit

Source Variable Description

Global

kibanaUrl

Kibana base URL. Useful for creating URL drilldowns that navigate within Kibana.

Context

context.panel

Context provided by current dashboard panel.

context.panel.id

ID of a panel.

context.panel.title

Title of a panel.

context.panel.filters

List of Kibana filters applied to a panel.
Tip: Use in combination with rison helper for internal Kibana navigations with carrying over current filters.

context.panel.query.query

Current query string.

context.panel.query.language

Current query language.

context.panel.timeRange.from
context.panel.timeRange.to

Current time picker values.
Tip: Use in combination with date helper to format date.

context.panel.indexPatternId
context.panel.indexPatternIds

Index pattern ids used by a panel.

context.panel.savedObjectId

ID of saved object behind a panel.

Single click

event.value

Value behind clicked data point.

event.key

Field name behind clicked data point

event.negate

Boolean, indicating whether clicked data point resulted in negative filter.

event.points

Some visualizations have clickable points that emit more than one data point. Use list of data points in case a single value is insufficient.

Example:

{{json event.points}}
{{event.points.[0].key}}
{{event.points.[0].value}} {{#each event.points}}key=value&{{/each}}

Note:

{{event.value}} is a shorthand for {{event.points.[0].value}}
{{event.key}} is a shorthand for {{event.points.[0].key}}

Row click

event.rowIndex

Number, representing the row that was clicked, starting from 0.

event.values

An array of all cell values for the raw on which the action will execute.

event.keys

An array of field names for each column.

event.columnNames

An array of column names.

Range selection

event.from
event.to

from and to values of the selected range as numbers.
Tip: Consider using date helper for date formatting.

event.key

Aggregation field behind the selected range, if available.
