| Parameter | Mandatory | Valid values | Default | Description |
| -- | -- | -- | -- | -- |
| `-v` | no | <switch> | | Enable verbose mode.
| `-p` | no | any valid ip address | 127.0.0.1 | Specify the service address. This is the address your Prometheus instance should point to.
| `-p` | no | any valid port number | 9586 | Specify the service port. This is the port your Prometheus instance should point to.
| `-n` | no | path to the wireguard configuration file | | This flag adds the *friendly_name* attribute to the exported entries. See [Friendly names](#friendly-names) for more details.
| `-s` | no | <switch> | off | Enable the allowed ip + subnet split mode for the labels.
