@Override
    public Metric get() {
        return metric;
    }
An implementation of {@link Provider} component of <code>Metric</code>. Because this class depends on {@link
MetricConsumerProvider}, any change to the consumer configuration will trigger reconfiguration of this component,
which in turn triggers reconfiguration of any component that depends on <code>Metric</code>.
