Package org.openspaces.admin.alert.alerts

Class CpuUtilizationAlert

java.lang.Object

org.openspaces.admin.alert.alerts.AbstractAlert

org.openspaces.admin.alert.alerts.CpuUtilizationAlert

All Implemented Interfaces:

Externalizable, Serializable, Alert

public class CpuUtilizationAlert
extends AbstractAlert

A CPU Utilization alert fired upon triggered CPU thresholds. The alert is raised when CPU crosses a 'high' threshold for a specified period of time. The alert is resolved when CPU crosses a 'low' threshold for a specified period of time.

These thresholds can be configured by using the CpuUtilizationAlertConfigurer.

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