SNMP Trap: Database Failover Status¶
A trap is generated when one or more nodes are down in a cluster.
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 VOSS-4-UC 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 - db constantly fails over
- .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 = ‘ERROR: The db is failing over constantly within 5 min’
- .iso.org.dod.internet.mgmt.mib-2.dismanEventMIB.dismanEventMIBNotificationPrefix. dismanEventMIBNotificationObjects.mteHotValue.0 = 1
- .iso.org.dod.internet.mgmt.mib-2.system.sysName.0 = standalone
Severity Messages:
- Info : INFO: The db failover status returned to normal
- Critical : ERROR: The db is failing over constantly within 5 min
