      public long count()
      Returns the current count of this metric. The returned value is always non-negative.

      As this metric is implemented using a LongAdder, the returned value is NOT an atomic snapshot; invocation in the absence of concurrent updates returns an accurate result, but concurrent updates that occur while the sum is being calculated might not be incorporated.
