Return `true` if this metric will actively record metrics, and `false` otherwise. If the returned value is `false`, the manipulator operations will have no effect. A metric will be inactive if either (1) it was not initialized with a valid metric identifier or (2) the associated metric category has been disabled (see the `MetricsManager` method `setCategoryEnabled`). Note that invoking this method is logically equivalent to the expression `0 != collector() && metricId().category()‐>enabled()`.
