# Configure Grafana Alerts Using Custom URL

Kloudfuse ships with fully enabled Grafana alerting.

If you also enable TLS and a DNS host name, you must update the default Grafana configuration in the `custom_values.yaml` file by merging it with the `root_url` that includes the DNS host name.

```yaml
grafana:
  replicas: 1
  grafana.ini:
    server:
    # Update this value if TLS is enabled
    root_url: "https://<REPLACE DNS HOST HERE>/grafana"
    smtp:
    ...
  envValueFrom:
  ...
```

If your `custom-values.yaml` file does not include a Grafana section, add the following content:

```yaml
# grafana - Configuration for the embedded Grafana included in Kloudfuse
grafana:
  # grafana.ini - Grafana server configuration settings
grafana.ini:
    server:
    # Update this value if TLS is enabled
      root_url: "https://<REPLACE DNS HOST HERE>/grafana"
      serve_from_sub_path: true
```
