SNMP Trap: NTP Offset
---------------------

A trap is generated when the NTP offset exceeds 1 second.

Identification

* The originating IP / hostname is used to identify the system generating the traps
* The NMS is responsible for associating traps with each managed system, along with clearing of alarms and escalation to the relevant system operator
* The trap OID is generic  for various SNMP events monitored by the system
* The SNMP system name is included as part of the variable binding to assist identification: 
* .iso.org.dod.internet.mgmt.mib-2.system.sysName.0 = standalone

Trap OID

.iso.org.dod.internet.mgmt.mib-2.dismanEventMIB.dismanEventMIBNotificationPrefix. dismanEventMIBNotifications.mteTriggerFired

Variable Bindings - NTP exceeds 1 second. 

* .iso.org.dod.internet.mgmt.mib-2.system.sysUpTime.0 = 2 minutes (12065)
* snmpTrapOID = mteTriggerFired
* .iso.org.dod.internet.mgmt.mib-2.dismanEventMIB.dismanEventMIBNotificationPrefix. dismanEventMIBNotificationObjects.mteHotTrigger.0 = 'WARNING: The ntp offset exceeds 1 second on <server info>'
* .iso.org.dod.internet.mgmt.mib-2.dismanEventMIB.dismanEventMIBNotificationPrefix. dismanEventMIBNotificationObjects.mteHotValue.0 = 1
* .iso.org.dod.internet.mgmt.mib-2.system.sysName.0 = standalone
