Return a collector for the specified metricId. Optionally specify a metrics manager used to provide the collector. If manager is 0, use the default metrics manager, if initialized; if manager is 0 and the default metrics manager has not been initialized, return 0. The behavior is undefined unless metricId is a valid metric id supplied by the MetricsRegistry of the indicated metrics manager.
