Create a configuration to define how Telegraf collects, processes, and writes
metrics. Telegraf Controller stores the configuration as TOML that you can use
across agents. Upload existing configurations, write raw TOML in the Code
Editor, or use the Telegraf Builder visual interface to manage and configure
plugins.

## Create a configuration

1. In the Telegraf Controller web interface, select **Configurations** in the
   navigation bar.
2. Click  **Add Config**.
3. Enter a configuration name and optional description.
4. Use the Telegraf Controller [Code Editor](#use-the-code-editor) or[Telegraf Builder](#use-the-telegraf-builder) to provide or build the
   Telegraf configuration TOML.
5. Click **Create Configuration**.

### Use the Code Editor

The Telegraf Controller **Code Editor** is an in-browser TOML editor that lets
you upload or manually write Telegraf configuration TOML.

*For detailed information about using the Code Editor, see[Use the Code Editor](/telegraf/controller/configs/ui/code-editor).*

### Use the Telegraf Builder

The **Telegraf Builder** is a visual interface for adding and configuring
Telegraf plugins in a Telegraf configuration. The Telegraf Builder is
currently a beta feature.

*For detailed information about using the Telegraf Builder, see[Use the Telegraf Builder](/telegraf/controller/configs/ui/telegraf-builder).*

#### The Telegraf Builder does not support all Telegraf plugins

We are in the process of adding support for more Telegraf plugins in the
Telegraf Builder. You can use plugins that are not currently supported by the
builder, but you must add and edit them with the Code Editor.

## Heartbeat output plugin

When adding a configuration, Telegraf Controller prepopulates the
configuration with a [Telegraf heartbeat output plugin](/telegraf/v1/output-plugins/heartbeat/).
This plugin reports agent information back to the Telegraf Controller heartbeat
API and lets you monitor the health of your deployed Telegraf agents.

```toml
[[outputs.heartbeat]]
url = "http://localhost:8000/agents/heartbeat"
instance_id = "&{agent_id}"
interval = "1m"
include = ["hostname", "statistics", "configs"]
token = "${TELEGRAF_CONTROLLER_TOKEN}"
```

To monitor agents with Telegraf Controller, include a heartbeat plugin in
your Telegraf configurations.

#### Authorize heartbeats using an API token

If Telegraf Controller requires authorization on the **Heartbeat** API,
include the `token` option in your heartbeat plugin configuration.
Provide a Telegraf Controller token with **write** permissions on the**Heartbeat** API.

We recommend defining the `TELEGRAF_CONTROLLER_TOKEN` environment variable
when starting Telegraf and using it to define the token in your heartbeat
plugin. On **Telegraf 1.38.x or earlier**, use `INFLUX_TOKEN` instead. For
details, see [Use API tokens](/telegraf/controller/tokens/use/#for-heartbeat-requests).

## Next steps

* Use [dynamic values](/telegraf/controller/configs/dynamic-values/)to keep configurations portable across environments.
* [Apply the configuration](/telegraf/controller/configs/use/) to your
  Telegraf agents.
