Each metric endpoint may support multiple child endpoints. For example, the `/v3/system/` metric has multiple child groups as `/v3/system/<child>`. Querying the parent endpoint returns metrics for all child groups. Querying a child group returns only metrics for that child.

### Per-bucket Metrics

# MinIO Healthcheck

MinIO server exposes three un-authenticated, healthcheck endpoints liveness probe and a cluster probe at `/minio/health/live` and `/minio/health/cluster` respectively.

## Liveness probe

This probe always responds with '200 OK'. Only fails if 'etcd' is configured and unreachable. When liveness probe fails, Kubernetes like platforms restart the container.

```
livenessProbe:
  httpGet:
    path: /minio/health/live
    port: 9000

	}
	return stats

// These are paths under the top-level /minio/metrics/v3 metrics endpoint. Each

// appended to the path. e.g. if the collector path is /bucket/api, the endpoint
// for the bucket "mybucket" would be /minio/metrics/v3/bucket/api/mybucket
