This document explains how to setup Prometheus and configure it to scrape data from MinIO servers.

## Prerequisites

To get started with MinIO, refer [MinIO QuickStart Document](https://min.io/docs/minio/linux/index.html#quickstart-for-linux).
Follow below steps to get started with MinIO monitoring using Prometheus.

### 1. Download Prometheus

      action.accept(keyList.get(i), valueList.get(i));
    }
  }

  @Override
  @CheckForNull
  public V get(@CheckForNull Object key) {
    int index = keySet.indexOf(key);
    return (index == -1) ? null : valueList.get(index);
  }

  @Override
  boolean isPartialView() {
    return keySet.isPartialView() || valueList.isPartialView();
  }

**FastAPI**는 모두 Pydantic을 기반으로 되어 있습니다.

이 모든 것이 실제로 어떻게 사용되는지에 대해서는 [자습서 - 사용자 안내서](tutorial/index.md){.internal-link target=_blank} 에서 더 많이 확인하실 수 있습니다.

## **FastAPI**에서의 타입 힌트

**FastAPI**는 여러 부분에서 타입 힌트의 장점을 취하고 있습니다.

**FastAPI**에서 타입 힌트와 함께 매개변수를 선언하면 장점은:

* **에디터 도움**.
* **타입 확인**.
