Hello,
You have to create your own variable in dashboard’s settings. You probably struggle with influxdb 2, you have one way to request tags:
import "influxdata/influxdb/schema"
schema.tagValues(
bucket: "bucketName",
tag: "tagName"
)
Others ways return only one row.
If you are used to influx 1 I advice to stay on it and get ride of influxdb for long term.
Best regards
