    You may do it this way:
     // TODO(tuananh): I don't know why I cannot use foreachpair instead.
            foreachpair (const MetricType& metricType, const auto& metrics, 
metricsMap) {
              foreachpair (const string& key, double value, metrics) {
                switch (metricType) {
                  case MetricType::COUNTER:
                  {
                    Metric metric;
                    metric.set_name(key);
                    metric.set_value(value);
                    _getMetrics->add_counters()->CopyFrom(metric);
                    break;
                  }
