### Events with Failures

When an operation fails, a failure method is called. This is `connectFailed()` for failures while building a connection to the server, and `callFailed()` when the HTTP call fails permanently. When a failure happens it is possible that a `start` event won’t have a corresponding `end` event.

Nous pouvons alors remplacer la dépendance « dependable » `common_parameters` ci‑dessus par la classe `CommonQueryParams` :

{* ../../docs_src/dependencies/tutorial002_an_py310.py hl[11:15] *}

Faites attention à la méthode `__init__` utilisée pour créer l'instance de la classe :

{* ../../docs_src/dependencies/tutorial002_an_py310.py hl[12] *}

... il a les mêmes paramètres que notre précédent `common_parameters` :

### Gérer les fichiers et async { #files-and-async }

Dans la plupart des cas, les objets de type fichier ne sont pas compatibles avec `async` et `await` par défaut.

Par exemple, ils n'ont pas de `await file.read()`, ni de `async for chunk in file`.

        info.setCapability(capability);

        return info;
    }

    private void encodeSockaddr(byte[] buffer, int offset) {
        // MS-SMB2: SockAddr_Storage field is 128 bytes
        // Clear the entire field first
        for (int i = 0; i < 128; i++) {
            buffer[offset + i] = 0;
        }

        if (ipv6) {
            // IPv6 sockaddr_in6 structure (Windows AF_INET6 = 23)

        // Verify the round trip preserves the value
        // Note: We can't directly access endOfFile field, but toString contains it
        assertEquals(original.toString(), decoded.toString());
    }

### 5. Start Prometheus

Start (or) Restart Prometheus service by running

```sh
./prometheus --config.file=prometheus.yml
```

Here `prometheus.yml` is the name of configuration file. You can now see MinIO metrics in Prometheus dashboard. By default Prometheus dashboard is accessible at `http://localhost:9090`.
