public class WindowedCount extends WindowedSum
SampledStat that maintains a simple count of what it has seen.
This is a special kind of WindowedSum that always records a value of 1 instead of the provided value.
In other words, it counts the number of
SampledStat.record(MetricConfig, double, long) invocations,
instead of summing the recorded values.
