NotificationOriginatorImpl

public NotificationOriginatorImpl(org.snmp4j.Session session,
                                  VACM vacm,
                                  SysUpTime sysUpTime,
                                  SnmpTargetMIB targetMIB,
                                  SnmpNotificationMIB notificationMIB)

Creates a notification originator.

Parameters:

session - the SNMP Session instance to be used to send the notifications/informs.

vacm - the VACM to be used to check access for notifications.

sysUpTime - the sysUpTime instance to be used to determine sysUpTime.0 when sending notifications without specifically specified sysUpTime.

targetMIB - the SnmpTargetMIB containing notification target information.

notificationMIB - SnmpNotificationMIB

NotificationOriginatorImpl

public NotificationOriginatorImpl(org.snmp4j.Session session,
                                  VACM vacm,
                                  SysUpTime sysUpTime,
                                  SnmpTargetMIB targetMIB,
                                  SnmpNotificationMIB notificationMIB,
                                  SnmpCommunityMIB communityMIB)

Creates a notification originator.

Parameters:

session - the Snmp instance to be used to send the notifications/informs.

vacm - the VACM to be used to check access for notifications.

sysUpTime - the sysUpTime instance to be used to determine sysUpTime.0 when sending notifications without specifically specified sysUpTime.

targetMIB - the SnmpTargetMIB containing notification target information.

notificationMIB - the SnmpNotificationMIB containing notification filtering information.

communityMIB - the community MIB for coexistence information.

Method Detail

notify

public Object notify(org.snmp4j.smi.OctetString context,
                     org.snmp4j.smi.OID notificationID,
                     org.snmp4j.smi.VariableBinding[] vbs)

Sends notifications (traps) to all appropriate notification targets.

Specified by:

notify in interface NotificationOriginator

Parameters:

context - the context name of the context on whose behalf this notification has been generated.

notificationID - the object ID that uniquely identifies this notification. For SNMPv1 traps, the notification ID has to be build using the rules provided by RFC 2576.

vbs - an array of VariableBinding instances representing the payload of the notification.

Returns:

an array of ResponseEvent instances. Since the NotificationOriginator determines on behalf of the SNMP-NOTIFICTON-MIB contents whether a notification is sent as trap/notification or as inform request, the returned array contains an element for each addressed target, but only a response PDU for inform targets.

setContextEngineID

protected void setContextEngineID(org.snmp4j.ScopedPDU scopedPDU,
                                  org.snmp4j.smi.OctetString context,
                                  org.snmp4j.smi.OID notificationID)

Sets the context engine ID of the scoped PDU to the local engine ID provided by the targetMIB member.

Parameters:

scopedPDU - the scopedPDU to modify.

context - the context associated with the notification/inform PDU.

notificationID - the notification ID of the notification/inform PDU.

Since:

1.2.1

notify

public Object notify(org.snmp4j.smi.OctetString context,
                     org.snmp4j.smi.OID notificationID,
                     org.snmp4j.smi.TimeTicks sysUpTime,
                     org.snmp4j.smi.VariableBinding[] vbs)

Description copied from interface: NotificationOriginator

Sends notifications (traps) to all appropriate notification targets. The targets to notify are determined through the SNMP-TARGET-MIB and the SNMP-NOTIFICATION-MIB.

Specified by:

notify in interface NotificationOriginator

Parameters:

context - the context name of the context on whose behalf this notification has been generated.

notificationID - the object ID that uniquely identifies this notification. For SNMPv1 traps, the notification ID has to be build using the rules provided by RFC 2576.

sysUpTime - the value of the sysUpTime for the context context. This value will be included in the generated notification as sysUpTime.0.

vbs - an array of VariableBinding instances representing the payload of the notification.

Returns:

an array of ResponseEvent instances. Since the NotificationOriginator determines on behalf of the SNMP-NOTIFICTON-MIB contents whether a notification is sent as trap/notification or as inform request, the returned array contains an element for each addressed target, but only a response PDU for inform targets.

setSession

public void setSession(org.snmp4j.Session snmpSession)

Sets the SNMP session to used by this notification originator for sending notifications.

Parameters:

snmpSession - the Snmp instance to be used to send the notifications/informs.

Since:

1.9.1

addNotificationLogListener

public void addNotificationLogListener(NotificationLogListener l)
