You can use simple tools like `htop` to see the CPU and RAM used in your server or the amount used by each process. Or you can use more complex monitoring tools, which may be distributed across servers, etc.

## Recap

      System.out.println("Response 2 succeeded: " + response);
    } catch (IOException e) {
      System.out.println("Response 2 failed: " + e);
    }
  }

  public static void main(String... args) throws Exception {
    new PerCallSettings().run();
  }

      if (!response.isSuccessful()) throw new IOException("Unexpected code " + response);

      System.out.println(response.body().string());
    }
  }

  public static void main(String... args) throws Exception {
    new PreemptiveAuth().run();
  }

  static final class BasicAuthInterceptor implements Interceptor {
    private final String credentials;
    private final String host;

It's relatively tightly coupled with relational databases (like MySQL or PostgreSQL), so, having a NoSQL database (like Couchbase, MongoDB, Cassandra, etc) as the main store engine is not very easy.

      for (Certificate certificate : response.handshake().peerCertificates()) {
        System.out.println(CertificatePinner.pin(certificate));
      }
    }
  }

  public static void main(String... args) throws Exception {
    new CertificatePinning().run();
  }

from fastapi.testclient import TestClient

from .main import app

    response = client.get("/items/foo", headers={"X-Token": "coneofsilence"})
    assert response.status_code == 200
    assert response.json() == {
        "id": "foo",
        "title": "Foo",
        "description": "There goes my hero",
    }

## Jalankan kode

Semua blok-blok kode dapat disalin dan digunakan langsung (Mereka semua sebenarnya adalah file python yang sudah teruji).

Untuk menjalankan setiap contoh, salin kode ke file `main.py`, dan jalankan `uvicorn` dengan:

<div class="termy">

```console
$ uvicorn main:app --reload

<span style="color: green;">INFO</span>:     Uvicorn running on http://127.0.0.1:8000 (Press CTRL+C to quit)

---

Si vous utilisez Pycharm, vous pouvez :

- Ouvrir le menu "Run".
- Sélectionnez l'option "Debug...".
- Un menu contextuel s'affiche alors.
- Sélectionnez le fichier à déboguer (dans ce cas, `main.py`).

Il démarrera alors le serveur avec votre code **FastAPI**, s'arrêtera à vos points d'arrêt, etc.
