Examples of org.voltdb.client.ClientStats.kPercentileLatencyAsDouble()

org.voltdb.client.ClientStats.kPercentileLatencyAsDouble()

Using the latency bucketing statistics gathered by the client, estimate the k-percentile latency value for the time period covered by this stats instance.

For example, k=.5 returns an estimate of the median. k=0 returns the minimum. k=1.0 returns the maximum.

Latencies longer than the highest trackable value (10 seconds) will be reported as multiple entries at the highest trackable value
@param percentile A floating point number between 0.0 and 1.0. @return An estimate of k-percentile latency in whole milliseconds.
