v1.fieldKeys() function

Flux 0.68.0 – 0.88.0

v1.fieldKeys() was deprecated in Flux v0.88.0 in favor of schema.fieldKeys().

The v1.fieldKeys() function returns field keys in a bucket. The return value is always a single table with a single column, _value.

import "influxdata/influxdb/v1"

v1.fieldKeys(
  bucket: "example-bucket",
  predicate: (r) => true,
  start: -30d
)

Parameters

bucket

The bucket to list field keys from.

predicate

The predicate function that filters field keys. Default is (r) => true.

start

The oldest time to include in results. Default is -30d.

Relative start times are defined using negative durations. Negative durations are relative to now. Absolute start times are defined using time values.

Examples

import "influxdata/influxdb/v1"

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

Function definition

package v1

fieldKeys = (bucket, predicate=(r) => true, start=-30d) =>
  tagValues(bucket: bucket, tag: "_field", predicate: predicate, start: start)

Used functions: [v1.tagValues]((/flux/v0.x/stdlib/influxdata/influxdb/v1/tagvalues/)
