Package akka.cluster.metrics

Class NodeMetrics

java.lang.Object

akka.cluster.metrics.NodeMetrics

All Implemented Interfaces:

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

public final class NodeMetrics
extends java.lang.Object
implements scala.Product, java.io.Serializable

The snapshot of current sampled health metrics for any monitored process. Collected and gossipped at regular intervals for dynamic cluster management strategies.

Equality of NodeMetrics is based on its address.

param: address Address of the node the metrics are gathered at param: timestamp the time of sampling, in milliseconds since midnight, January 1, 1970 UTC param: metrics the set of sampled Metric
