How to use a InfluxDB-tag value in a grafana legend?

I have a InfluxDB dataseries. It stores one information about mulitple machines. I distingsh between these machines with a tag. I can display the information for all three machines at once using a "Group by tag(machine)" clause. the name of the legends is "table.derivative {machine: 1}", "table.derivative {machine: 2}" and so on. How can I change it to "machine 1", "machine 2" and so on?

So far I came across this suggesting to use $groupby (or $g ?), but both are just added a literally.

If you are using InfluxDB with Flux query language, use the following in the Display Name

  • ${__field.labels}
  • ${__field.labels.<tag_name>}

or in some cases this might work

  • ${__field.labels.name}

In Grafana, you can use alias patterns. There is a description of alias patterns at the bottom of the metrics tab:

enter image description here

In your case, in the Alias By field you would write $tag_machine.

Here is an InfluxDb example on the Grafana demo site that uses the Alias By field:

For me $_tag_TAGNAME worked ... none of the above worked for me ( even though I saw it in the help section of my instance of Grafana ...)
