aimosAlarmChanged

Module: AIMOS

OID (symbolic): AIMOS::aimosAlarmChanged

OID (numeric): 1.3.6.1.4.1.6408.201.4.6

Node type: NOTIFICATION-TYPE

Description: The aimosAlarmChanged notification is used when the severity of an uncleared alarm has changed. The alarm is correlated with the aimosAlarmNew notification by identical values in aimosAlarmListAlarmEventID.

The aimosAlarmChanged notification causes the A.I.M.O.S. SNMP Agent to create . one alarm list entry per affected organisation and . one alarm trap list entry per affected SNMP Manager containing the values of the notifications objects.

Examples

Send this trap to an SNMP manager — replace <manager> with the IP or hostname of your monitoring server (SNMPv2c):

snmptrap -v2c -c public <manager> '' AIMOS::aimosAlarmChanged
snmptrap -v2c -c public <manager> '' 1.3.6.1.4.1.6408.201.4.6

Listen for incoming traps on the manager host (-f keeps it in the foreground, -Lo prints to stdout — useful for testing):

snmptrapd -f -Lo -c /dev/null authCommunity log public

Example snmptrapd log entry:

zoo11-linux.zoo [UDP: [192.168.30.111]:52226->[192.168.30.10]:162]:
  DISMAN-EVENT-MIB::sysUpTimeInstance = Timeticks: (129952770) 15 days, 0:58:47.70
  SNMPv2-MIB::snmpTrapOID.0 = OID: AIMOS::aimosAlarmChanged

SNMPv3 example:

snmptrap -v3 -l authPriv -u snmpv3user -a SHA -A "AuthPass1" -x AES -X "PrivPass1" <manager> '' AIMOS::aimosAlarmChanged
