How to use a InfluxDB-tag value in a grafana legend?
In Grafana, you can use alias patterns. There is a description of alias patterns at the bottom of the metrics tab:
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:

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}
