# Using Subtrace with Flightcontrol

> Integrate your app with Subtrace on Flightcontrol

If you deploy your app using Flightcontrol, you can use Subtrace to monitor all its
requests. Here's how you can get started:

1. Add these lines to your `flightcontrol.json` file under the `target` section:

```json {3-4} theme={null}
"target": {
    "type": "fargate",
    "linuxCapabilities": {
        "add": ["SYS_PTRACE"]
    }
}
```

2. Add the `SUBTRACE_TOKEN` environment variable to Flightcontrol:

<img className="rounded-xl" src="https://mintcdn.com/subtrace/vZALhcQ_ScTTRTH9/images/flightcontrol/env-var.png?fit=max&auto=format&n=vZALhcQ_ScTTRTH9&q=85&s=315254df9bf7776de2b334ab9a217d79" width="1311" height="1312" data-path="images/flightcontrol/env-var.png" />

<Tip>
  If you don’t have a Subtrace token yet, go to the Tokens page on the [dashboard](https://subtrace.dev/dashboard) and
  create a tracer token.
</Tip>

3. Deploy your app as you normally do on Flightcontrol.

That's it! You can now visit your app and make some requests to see them automatically appear in the Subtrace
dashboard.
