Class ProcessingUnitInstanceMemberAliveIndicatorAlert

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

All Implemented Interfaces:

Externalizable, Serializable, Alert

public class ProcessingUnitInstanceMemberAliveIndicatorAlert
extends AbstractAlert

A processing unit instance fault-detection alert triggered when a Grid Service Manager fails to monitor a processing unit instance. The alert is first raised when the fault-detection mechanism suspects that a service is down, and once more when all fault-detection retry attempts have been exhausted. The alert is resolved if one the fault-detection retry attempts succeeded.

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