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.

// Collector paths.
//
// These are paths under the top-level /minio/metrics/v3 metrics endpoint. Each
// of these paths returns a set of V3 metrics.
//
// Per-bucket metrics endpoints always start with /bucket and the bucket name is
// 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
