##### Resource (optional)

Optionally you can also collect resource metrics.

```yaml
scrape_configs:
- job_name: minio-job
  metrics_path: /minio/v2/metrics/resource
  scheme: http
  static_configs:
  - targets: ['localhost:9000']
```

### 4. Update `scrape_configs` section in prometheus.yml

	NEndpoints int
