Telegraf Controller

Use the Code Editor

Telegraf Controller is in Public Beta

Telegraf Controller is in public beta and will be part of the future Telegraf Enterprise offering. While in beta, Telegraf Controller is not meant for production use. The Telegraf Controller documentation is a work in progress, and we are actively working to improve it. If you have any questions or suggestions, please submit an issue. We welcome any and all contributions.

Beta expectations

Provide beta feedback

Use the Telegraf Controller Code Editor to upload, write, or edit raw Telegraf configuration TOML.

Telegraf Controller Code Editor

The Code Editor is the default view when managing a configuration. If it is not displayed, click the Code Editor tab.

Switching from the Code Editor to the Telegraf Builder

Switching from the Code Editor to the Telegraf Builder will reformat the TOML. When reformatting, Telegraf Builder does not preserve the following:

  • Comments
  • Indentation
  • Plugin Order

Upload TOML

To upload a Telegraf configuration file to Telegraf Controller, click Upload files to open a file selection dialogue box or drag and drop your configuration file into the Code Editor.

Telegraf Controller supports TOML-formatted files with the following extensions:

  • .toml
  • .conf
  • .txt

Uploaded configuration files fully replace any existing configuration TOML.

Manually write or edit TOML

The Code Editor is a feature-rich, browser-based editor that lets you write code using keyboard shortcuts similar to those in popular editors and IDEs.

InfluxDB Docker latest tag changing to InfluxDB 3 Core

On May 27, 2026, the latest tag for InfluxDB Docker images will point to InfluxDB 3 Core. To avoid unexpected upgrades, use specific version tags in your Docker deployments.

If using Docker to install and run InfluxDB, the latest tag will point to InfluxDB 3 Core. To avoid unexpected upgrades, use specific version tags in your Docker deployments. For example, if using Docker to run InfluxDB v2, replace the latest version tag with a specific version tag in your Docker pull command–for example:

docker pull influxdb:2
