grafana can visualize them for all the nodes

```yaml
scrape_configs:
- job_name: minio-job
  metrics_path: /minio/v2/metrics/node
  scheme: http
  static_configs:
  - targets: ['server1:9000','server2:9000','server3:9000','server4:9000']
```

##### Resource (optional)

Optionally you can also collect resource metrics.

```yaml
scrape_configs:
- job_name: minio-job

	done

	disown ${pid1}

	"${MINIO[@]}" --address ":$((start_port + 2))" $args >"${WORK_DIR}/dist-minio-server2.log" 2>&1 &
	pid2=$!
	disown $pid2

	"${MINIO[@]}" --address ":$((start_port + 3))" $args >"${WORK_DIR}/dist-minio-server3.log" 2>&1 &
	pid3=$!
	disown $pid3
