public class MetricsResource
extends BasicRestResource

Child-resource flavor of the /metrics endpoint.

Mounts as a routed child via @Rest(children=MetricsResource.class) under the subtree /metrics and delegates to a shared MetricsManager worker — the same logic the mixin flavor uses, so the two forms cannot drift. Degrades to HTTP 501 when no scrapeable registry bean is present.
