All Implemented Interfaces:

java.io.Serializable, scala.Equals, scala.Product

public class HeartbeatHistory
extends java.lang.Object
implements scala.Product, scala.Serializable

Holds the heartbeat statistics for a specific node Address. It is capped by the number of samples specified in maxSampleSize.

The stats (mean, variance, stdDeviation) are not defined for for empty HeartbeatHistory, i.e. throws AritmeticException.
