There are multiple ways to execute Flux queries with InfluxDB Enterprise and Chronograf v1.8+. This guide covers the different options:

1. Chronograf's Data Explorer
2. Influx CLI
3. InfluxDB API

Before attempting these methods, make sure Flux is enabled by setting flux-enabled = true in the [http] section of your InfluxDB configuration file.

Chronograf's Data Explorer

Chronograf v1.8+ supports Flux in its Data Explorer. Flux queries can be built, executed, and visualized from within the Chronograf user interface.

Influx CLI

To start an interactive Flux read-eval-print-loop (REPL) with the InfluxDB Enterprise 1.10+ influx CLI, run the influx command with the following flags:

• -type=flux
• -path-prefix=/api/v2/query

{{% note %}} If authentication is enabled on your InfluxDB instance, use the -username flag to provide your InfluxDB username and the -password flag to provide your password. {{% /note %}}

Enter an interactive Flux REPL

{{< code-tabs-wrapper >}} {{% code-tabs %}} No Auth Auth Enabled {{% /code-tabs %}} {{% code-tab-content %}}

influx -type=flux -path-prefix=/api/v2/query

{{% /code-tab-content %}} {{% code-tab-content %}}

influx -type=flux \
  -path-prefix=/api/v2/query \
  -username myuser \
  -password PasSw0rd

{{% /code-tab-content %}} {{< /code-tabs-wrapper >}}

Any Flux query can be executed within the REPL.

Submit a Flux query via parameter

Flux queries can also be passed to the Flux REPL as a parameter using the influx CLI's -type=flux option and the -execute parameter. The accompanying string is executed as a Flux query and results are output in your terminal.

{{< code-tabs-wrapper >}} {{% code-tabs %}} No Auth Auth Enabled {{% /code-tabs %}} {{% code-tab-content %}}

influx -type=flux \
  -path-prefix=/api/v2/query \
  -execute '<flux query>'

{{% /code-tab-content %}} {{% code-tab-content %}}

influx -type=flux \
  -path-prefix=/api/v2/query \
  -username myuser \
  -password PasSw0rd \
  -execute '<flux query>'

{{% /code-tab-content %}} {{< /code-tabs-wrapper >}}

Submit a Flux query via via STDIN

Flux queries an be piped into the influx CLI via STDIN. Query results are otuput in your terminal.

{{< code-tabs-wrapper >}} {{% code-tabs %}} No Auth Auth Enabled {{% /code-tabs %}} {{% code-tab-content %}}

echo '<flux query>' | influx -type=flux -path-prefix=/api/v2/query

{{% /code-tab-content %}} {{% code-tab-content %}}

echo '<flux query>' | influx -type=flux \
  -path-prefix=/api/v2/query \
  -username myuser \
  -password PasSw0rd

{{% /code-tab-content %}} {{< /code-tabs-wrapper >}}

InfluxDB API

Flux can be used to query InfluxDB through InfluxDB's /api/v2/query endpoint. Queried data is returned in annotated CSV format.

In your request, set the following:

• Accept header to application/csv
• Content-type header to application/vnd.flux
• If authentication is enabled on your InfluxDB instance, Authorization header to Token <username>:<password>

This allows you to POST the Flux query in plain text and receive the annotated CSV response.

Below is an example curl command that queries InfluxDB using Flux:

{{< code-tabs-wrapper >}} {{% code-tabs %}} No Auth Auth Enabled {{% /code-tabs %}} {{% code-tab-content %}}

curl -XPOST localhost:8086/api/v2/query -sS \
  -H 'Accept:application/csv' \
  -H 'Content-type:application/vnd.flux' \
  -d 'from(bucket:"telegraf")
          |> range(start:-5m)
          |> filter(fn:(r) => r._measurement == "cpu")'

{{% /code-tab-content %}} {{% code-tab-content %}}

curl -XPOST localhost:8086/api/v2/query -sS \
  -H 'Accept:application/csv' \
  -H 'Content-type:application/vnd.flux' \
  -H 'Authorization: Token <username>:<password>' \
  -d 'from(bucket:"telegraf")
          |> range(start:-5m)
          |> filter(fn:(r) => r._measurement == "cpu")'

{{% /code-tab-content %}} {{< /code-tabs-wrapper >}}
