Flux provides functions that let you explore the structure and schema of your data stored in InfluxDB.

• List buckets
• List measurements
• List field keys
• List tag keys
• List tag values

List buckets

Use the buckets() function to list buckets in your organization.

buckets()

List measurements

Use the v1.measurements() function to list measurements in a bucket.

import "influxdata/influxdb/v1"

v1.measurements(bucket: "example-bucket")

List field keys

Use the v1.fieldKeys function to list field keys in a bucket.

import "influxdata/influxdb/v1"

v1.fieldKeys(bucket: "example-bucket")

List fields in a measurement

Use the v1.measurementFieldKeys function to list field keys in a measurement.

import "influxdata/influxdb/v1"

v1.measurementFieldKeys(
  bucket: "example-bucket",
  measurement: "example-measurement"
)

List tag keys

Use the v1.tagKeys() function to list tag keys in a bucket.

import "influxdata/influxdb/v1"

v1.tagKeys(bucket: "example-bucket")

List tag keys in a measurement

Use the v1.measurementTagKeys function to list tag keys in a measurement. This function returns results from the last 30 days.

import "influxdata/influxdb/v1"

v1.measurementTagKeys(
  bucket: "example-bucket",
  measurement: "example-measurement"
)

List tag values

Use the v1.tagValues() function to list tag values for a given tag in a bucket.

import "influxdata/influxdb/v1"

v1.tagValues(bucket: "example-bucket", tag: "example-tag")

List tag values in a measurement

Use the v1.measurementTagValues function to list tag values for a given tag in a measurement. This function returns results from the last 30 days.

import "influxdata/influxdb/v1"

v1.measurementTagValues(
  bucket: "example-bucket",
  tag: "example-tag",
  measurement: "example-measurement"
)
