# fly doctor diag

Send diagnostic information about your applications back to Fly.io,

that you'd be sending us anyways in order to deploy, notably any Dockerfiles
you might have associated with this application.

## Usage

```
fly doctor diag [flags]
```

## Options

```
  -a, --app string      Application name
  -c, --config string   Path to application configuration file
      --force           Send diagnostics even if we can't find your local Fly.io app
  -h, --help            help for diag
```

## Global Options

```
  -t, --access-token string   Fly API Access Token
      --debug                 Print additional logs and traces
      --verbose               Verbose output
```
