json api key/value support for variables

[stefan-g]

I would like to use the json api to defines some variables in grafana from a json data source. The variable in grafana should be defined as key values pair but as i've seen in the documentation it does only support one field. Did i missed something or is it not possible to get a key and a value from a json? If it's not possible i think it would be a nice feature.

I'm not sure I understand the question. Dashboard variables in can only be strings or numbers, which is a limitation in Grafana rather than this plugin.

Could you give an example of how you'd want to use key/values in variables?

[stefan-g]

Yes, I have a metric label_value that is defined as a number (like 100,101,102,....). Each number has an assigned text. In grafana i would like to define a more userfriendly variable that shows the text instead of the number. Key/value pairs can be defined as customer variables (format is myKey:myValue, ....). I might have found a solution with regex but not sure if it works yet...

[marcusolsson]

If you'd like to be able to set an optional label for the variable value, there's an open feature request for this. Please add your thoughts in that thread if you think it would be helpful for your use case 🙏

Thanks for your answer. I'm looking for the same feature.
