# Cluster Metrics

MinIO collects the following metrics at the cluster level.
Metrics may include one or more labels, such as the server that calculated that metric.

These metrics can be obtained from any MinIO server once per collection by using the following URL:

```shell
https://HOSTNAME:PORT/minio/v2/metrics/cluster
```

Replace ``HOSTNAME:PORT`` with the hostname of your MinIO deployment.

    * この`dict`の値は`float`型です。（つまり、各項目の価格）

#### `Optional`

また、`Optional`を使用して、変数が`str`のような型を持つことを宣言することもできますが、それは「オプション」であり、`None`にすることもできます。

```Python hl_lines="1 4"
{!../../docs_src/python_types/tutorial009.py!}
```

ただの`str`の代わりに`Optional[str]`を使用することで、エディタは値が常に`str`であると仮定している場合に実際には`None`である可能性があるエラーを検出するのに役立ちます。

#### ジェネリック型

以下のように角括弧で型パラメータを取る型を:

* `List`
* `Tuple`
* `Set`
* `Dict`
