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
