> Current MutableHistogram do not reset min/max/sum after snapshot, so we affect by historical
data. For example when i monitor the QueueCallTime_mean, i see one host's QueueCallTime_mean
metric is high, but when i trace the host's regionserver log i see the QueueCallTime_mean
has been lower, but the metric is still high.
