Class StatisticsPeek<E extends Enum<E>>

java.lang.Object

io.rainfall.statistics.StatisticsPeek<E>

public class StatisticsPeek<E extends Enum<E>>
extends Object

A peek at the Statistics, used for statistics inspection. Holds the: - timestamp - periodic average latency (periodic average latency for one observed domain) - cumulative average latency (cumulative average latency for one observed domain) - total periodic average latency (periodic average latency for all observed domains) - total cumulative average latency (cumulative average latency for one observed domain) - periodic counter (periodic nb of operations for one observed domain) - cumulative counter (cumulative nb of operations for one observed domain) - total periodic counter (periodic nb of operations for all observed domains) - total cumulative counter (cumulative nb of operations for one observed domain) - periodic TPS (periodic TPS for one observed domain) - cumulative TPS (cumulative TPS for one observed domain) - total periodic TPS (periodic TPS for all observed domains) - total cumulative TPS (cumulative TPS for one observed domain) - HdrHistogram : percentiles of measures latencies
