SNMP Trap: Mailbox Status¶
A trap is generated when the local mailbox reaches 200 plus emails.
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 - Mailbox email messages reach 200
.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 total messages in the local mailbox for %s has reached in excess of 200’
.iso.org.dod.internet.mgmt.mib-2.dismanEventMIB.dismanEventMIBNotificationPrefix. dismanEventMIBNotificationObjects.mteHotValue.0 = 1
.iso.org.dod.internet.mgmt.mib-2.system.sysName.0 = standalone
Variable Bindings - Mailbox email messages reach 500
.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 = ‘INFO: Messages for <server info> auto archived as it reached more than 500’
.iso.org.dod.internet.mgmt.mib-2.dismanEventMIB.dismanEventMIBNotificationPrefix. dismanEventMIBNotificationObjects.mteHotValue.0 = 1
.iso.org.dod.internet.mgmt.mib-2.system.sysName.0 = standalone
