Class PhysicalMemoryUtilizationAlert

java.lang.Object
  org.openspaces.admin.alert.alerts.AbstractAlert
      org.openspaces.admin.alert.alerts.PhysicalMemoryUtilizationAlert

All Implemented Interfaces:

Externalizable, Serializable, Alert

public class PhysicalMemoryUtilizationAlert
extends AbstractAlert

A physical memory utilization alert, fired upon triggered machine physical memory thresholds. The alert is raised when memory crosses a 'high' threshold for a specified period of time. The alert is resolved when memory crosses a 'low' threshold for a specified period of time.

These thresholds can be configured by using the PhysicalMemoryUtilizationAlertConfigurer.

This alert will be received on the call to AlertTriggeredEventListener.alertTriggered(Alert) for registered listeners.
