Package akka.cluster.metrics

Class StandardMetrics.HeapMemory

java.lang.Object

akka.cluster.metrics.StandardMetrics.HeapMemory

All Implemented Interfaces:

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

Enclosing class:

StandardMetrics

public static final class StandardMetrics.HeapMemory
extends java.lang.Object
implements scala.Product, scala.Serializable

The amount of used and committed memory will always be <= max if max is defined. A memory allocation may fail if it attempts to increase the used memory such that used > committed even if used <= max is true (e.g. when the system virtual memory is low).

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: used the current sum of heap memory used from all heap memory pools (in bytes) param: committed the current sum of heap memory guaranteed to be available to the JVM from all heap memory pools (in bytes). Committed will always be greater than or equal to used. param: max the maximum amount of memory (in bytes) that can be used for JVM memory management. Can be undefined on some OS.
