List buckets

List all buckets in the current organization.

Flux functions: [buckets()](/{{< latest "flux" >}}/stdlib/universe/buckets/), [rename()](/{{< latest "flux" >}}/stdlib/universe/rename/), [keep()](/{{< latest "flux" >}}/stdlib/universe/keep/)

buckets()
  |> rename(columns: {"name": "_value"})
  |> keep(columns: ["_value"])

List measurements

List all measurements in a specified bucket.

Flux package: [InfluxDB schema](/{{< latest "flux" >}}/stdlib/influxdata/influxdb/schema/)
Flux functions: [schema.measurements()](/{{< latest "flux" >}}/stdlib/influxdata/influxdb/schema/measurements/)

import "influxdata/influxdb/schema"

schema.measurements(bucket: "bucket-name")

List fields in a measurement

List all fields in a specified bucket and measurement.
