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
