# 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.

     * } catch (NamingException ne) {

 * <h2>When to Use DomUtils</h2>
 * <p>Use DomUtils methods when you need:
 * <ul>
 * <li>Maven-specific element ordering (insertNewElement, insertContentElement)</li>
 * <li>High-level helpers (addGAVElements, createDependency, createPlugin)</li>
 * <li>Null-safe operations (updateElementContent, removeElement)</li>
 * <li>Update-or-create patterns (updateOrCreateChildElement)</li>
 * </ul>

One of those distributed container management systems like Kubernetes normally has some integrated way of handling **replication of containers** while still supporting **load balancing** for the incoming requests. All at the **cluster level**.

## **FastAPI**'s `OAuth2PasswordBearer` { #fastapis-oauth2passwordbearer }

**FastAPI** provides several tools, at different levels of abstraction, to implement these security features.

In this example we are going to use **OAuth2**, with the **Password** flow, using a **Bearer** token. We do that using the `OAuth2PasswordBearer` class.
