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.
See also CumulativeCount
for a non-sampled version of this metric.Constructor and Description |
