##### Node (optional)

Optionally you can also collect per node metrics. This needs to be done on a per server instance.
The scrape configurations should use all the servers under `targets` so that graphing systems like
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:

	ErrTooManyRequests
	ErrInvalidRequest
	ErrTransitionStorageClassNotFoundError
	// MinIO storage class error codes
	ErrInvalidStorageClass
	ErrBackendDown
	// Add new extended error codes here.
	// Please open a https://github.com/minio/minio/issues before adding
	// new error codes here.

	ErrMalformedJSON
	ErrAdminNoSuchUser
	ErrAdminNoSuchUserLDAPWarn
	ErrAdminLDAPExpectedLoginName
