```sh
./prometheus --config.file=prometheus.yml
```

 * Circuit breaker pattern implementation for SMB operations.
 * Prevents cascading failures by temporarily blocking requests to a failing service.
 *
 * The circuit breaker has three states:
 * - CLOSED: Normal operation, requests pass through
 * - OPEN: Service is failing, requests are blocked
 * - HALF_OPEN: Testing if service has recovered

For example, you can configure STS with Client Grants (KeyCloak) using the guides at [MinIO STS Quickstart Guide](https://docs.min.io/community/minio-object-store/developers/security-token-service.html) and [KeyCloak Configuration Guide](https://github.com/minio/minio/blob/master/docs/sts/keycloak.md). Once this is done, STS credentials can be generated:
