# Poll endpoint "/metrics"

Extended internal information on the status of the Ruuvi Gateway can be obtained by polling the endpoint "/metrics".

On the "Access Settings" page, enable bearer authentication and set the bearer token:

After that it is possible to poll data using the "/metrics" endpoint:

```shell
curl -v http://<RUUVI_GW_IP>/metrics 
    -H "Authorization: Bearer Uj+4tj24unVekco/lTLTRyxUfv1J8M6U+sbNsKTWRr0="
```
