### Using `sling conns`

Here are examples of setting a connection named `PROMETHEUS`. We must provide the `type=prometheus` property:

{% code overflow="wrap" %}

```bash
$ sling conns set PROMETHEUS type=prometheus http_url=<http_url> api_key=<api_key> 
```

{% endcode %}

### Environment Variable

See [here](https://docs.slingdata.io/sling-cli/environment#dot-env-file-.env.sling) to learn more about the `.env.sling` file.

{% code overflow="wrap" %}

```bash
export PROMETHEUS='{type: prometheus, http_url: "<http_url>", api_key: "<api_key>" }'
```

{% endcode %}

### Sling Env File YAML

See [here](https://docs.slingdata.io/sling-cli/environment#sling-env-file-env.yaml) to learn more about the sling `env.yaml` file.

```yaml
connections:
  PROMETHEUS:
    type: prometheus
    http_url: <http_url>
    api_key: <api_key>
    tls: true # if TLS connection needed
```
