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.InitializingBean

public class Trapd
extends AbstractServiceDaemon
implements PausableFiber, TrapProcessorFactory, TrapNotificationListener, org.springframework.beans.factory.InitializingBean

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

Constructor Detail

Trapd

public Trapd()

Constructs a new Trapd object that receives and forwards trap messages via JSDT. The session is initialized with the default client name of OpenNMS.trapd. The trap session is started on the default port, as defined by the SNMP libarary.

SnmpTrapSession

Method Detail

createTrapProcessor

public TrapProcessor createTrapProcessor()

Specified by:

createTrapProcessor in interface TrapProcessorFactory

trapReceived

public void trapReceived(TrapNotification trapNotification)

Specified by:

trapReceived in interface TrapNotificationListener

onInit

public void onInit()

Specified by:

onInit in class AbstractServiceDaemon

onStart

public void onStart()

Create the SNMP trap session and create the communication channel to communicate with eventd.

Overrides:

onStart in class AbstractServiceDaemon

Throws:

UndeclaredThrowableException - if an unexpected database, or IO exception occurs.

See Also:

SnmpTrapSession, SnmpTrapHandler

onPause

public void onPause()

Pauses Trapd

Overrides:

onPause in class AbstractServiceDaemon

onResume

public void onResume()

Resumes Trapd

Overrides:

onResume in class AbstractServiceDaemon

onStop

public void onStop()

Stops the currently running service. If the service is not running then the command is silently discarded.

onStop in class AbstractServiceDaemon

getStatus

public int getStatus()

Returns the current status of the service.

Specified by:

getStatus in interface Fiber

Overrides:

getStatus in class AbstractServiceDaemon

Returns:

The service's status.
