Method Detail

addPerformanceReportListener

public void addPerformanceReportListener(PerformanceReportListener listener,
                                         float intervalInSeconds)
                                  throws java.rmi.RemoteException

This method is used to add a listener that receives periodic performance updates.

Parameters:

listener - callback for performance reports.

intervalInSeconds - interval between performance reports

Throws:

java.rmi.RemoteException - in the case of a network error.

removePerformanceReportListener

public void removePerformanceReportListener(PerformanceReportListener listener)
                                     throws java.rmi.RemoteException

This method is used to remove a listener that receives periodic performance updates.

Parameters:

listener - callback for performance reports.

Throws:

java.rmi.RemoteException - in the case of a network error.

addUnitReportListener

public void addUnitReportListener(UnitReportListener listener)
                           throws java.rmi.RemoteException

This method is used to add a listener that receives unit fault reports. A unit report indicates online, offline, and degraded status for a component or capability provided by a component. These reports are generated when faults occur, not at periodic intervals.

Parameters:

listener - callback for unit reports.

Throws:

java.rmi.RemoteException - in the case of a network error.

removeUnitReportListener

public void removeUnitReportListener(UnitReportListener listener)
                              throws java.rmi.RemoteException

This method is used to remove a listener that receives unit fault reports.

Parameters:

listener - callback for unit reports.

Throws:

java.rmi.RemoteException - in the case of a network error.

addHeartbeatListener

public void addHeartbeatListener(HeartbeatListener listener,
                                 float intervalInSeconds)
                          throws java.rmi.RemoteException

This method is used to add a listener that receives periodic heartbeat events. Heartbeats are events that are used to monitor critical components on a frequent basis. A missed heartbeat indicates an exception condition.

Parameters:

listener - callback for heartbeats.

intervalInSeconds - interval between heartbeats.

Throws:

java.rmi.RemoteException - in the case of a network error.

removeHeartbeatListener

public void removeHeartbeatListener(HeartbeatListener listener)
                             throws java.rmi.RemoteException

This method is used to remove a listener that receives periodic heartbeat events.

Parameters:

listener - callback for heartbeats.

Throws:

java.rmi.RemoteException - in the case of a network error.
