Class Trapd

java.lang.Object

org.opennms.netmgt.daemon.AbstractServiceDaemon

org.opennms.netmgt.trapd.Trapd

All Implemented Interfaces:

Fiber, PausableFiber, SpringServiceDaemon, ServiceDaemon, TrapNotificationListener, TrapProcessorFactory, org.springframework.beans.factory.DisposableBean, org.springframework.beans.factory.InitializingBean

public class Trapd
extends AbstractServiceDaemon
implements TrapProcessorFactory, TrapNotificationListener

The Trapd listens for SNMP traps on the standard port(162). Creates a SnmpTrapSession and implements the SnmpTrapHandler to get callbacks when traps are received.

The received traps are converted into XML and sent to eventd.

Note: Trapd is a PausableFiber so as to receive control events. However, a 'pause' on Trapd has no impact on the receiving and processing of traps.

createTrapProcessor

Specified by:

createTrapProcessor in interface TrapProcessorFactory

Returns:

a TrapProcessor object.

trapReceived

public void trapReceived(TrapNotification trapNotification)
