Create a metric object to collect values for the specified `metricId`. Optionally specify a metrics `manager` used to provide a collector for `metricId`. If `manager` is 0, use the default metrics manager, if initialized; if `manager` is 0 and the default metrics manager has not been initialized, place this metric object in the inactive state (i.e., `isActive()` is `false`) in which case instance methods that would otherwise update the metric will have no effect. The behavior is undefined unless `metricId` is a valid id returned by the `MetricRepository` object owned by the indicated metrics manager.
