Each endpoint below can be queried at different intervals as needed via a scrape configuration in Prometheus or a compatible metrics collection tool.

For ease of configuration, each (non-empty) parent of the path serves all metric endpoints that are at descendant paths. For example, to query all system metrics one needs to only scrape `/minio/metrics/v3/system/`.

Contêineres Linux rodam usando o mesmo kernel Linux do hospedeiro (máquina, máquina virtual, servidor na nuvem, etc). Isso simplesmente significa que eles são muito leves (comparados com máquinas virtuais emulando um sistema operacional completo).

Dessa forma, contêineres consomem **poucos recursos**, uma quantidade comparável com rodar os processos diretamente (uma máquina virtual consumiria muito mais).

    ```

As in this case (without using `Annotated`) we have to replace the default value `None` in the function with `Query()`, we now need to set the default value with the parameter `Query(default=None)`, it serves the same purpose of defining that default value (at least for FastAPI).

So:

```Python
q: Union[str, None] = Query(default=None)
```
