Class ReplicationRedoLogSizeAlert

java.lang.Object
org.openspaces.admin.alert.alerts.AbstractAlert
org.openspaces.admin.alert.alerts.ReplicationRedoLogSizeAlert
All Implemented Interfaces:
Externalizable, Serializable, Alert
public class ReplicationRedoLogSizeAlert extends AbstractAlert
A replication redo-log size alert, fired upon redo-log increase, indicating that packets are not being sent from a source Space to it's target Space (backup or mirror). The alert is raised when red-log size crosses a specified 'high' threshold. The alert is resolved when the redo-log size goes below a specified 'low' threshold.

These thresholds can be configured by using the ReplicationRedoLogSizeAlertConfigurer.

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