URL variables

You can use variables in data links to link to specific portions of your visualizations. For more information about data links, refer to [Data links]({{< relref "../linking/data-links.md" >}}).

Note: These variables changed in 6.4 so if you have an older version of Grafana please use the version picker to select docs for an older version of Grafana.

Time variables

• __url_time_range - current dashboard's time range (i.e. ?from=now-6h&to=now)
• __from - current dashboard's time range from value
• __to - current dashboard's time range to value

Series variables

Series specific variables are available under __series namespace:

• __series.name - series name to the URL
• __series.labels.<LABEL> - label's value to the URL. If your label contains dots use __series.labels["<LABEL>"] syntax

Field variables

Field specific variables are available under __field namespace:

• __field.name - field name to the URL

Value variables

Value specific variables are available under __value namespace:

• __value.time - value's timestamp (Unix ms epoch) to the URL (i.e. ?time=1560268814105)
• __value.raw - raw value
• __value.numeric - numeric representation of a value
• __value.text - text representation of a value
• __value.calc - calculation name if the value is result of calculation

Template variables

When linking to another dashboard that uses template variables, you can use var-myvar=${myvar} syntax (where myvar is a name of template variable) to use current dashboard's variable value. If you want to add all of the current dashboard's variables to the URL use __all_variables variable.
