alarmClearState
Module: ALARM-MIB
OID (symbolic): ALARM-MIB::alarmClearState
OID (numeric): 1.3.6.1.2.1.118.0.3
Node type: NOTIFICATION-TYPE
Description: An instance of the alarm indicated by alarmActiveModelPointer has been cleared against
the entity indicated by alarmActiveResourceId.
The agent must throttle the generation of consecutive alarmActiveClear traps so that there is at least a two-second gap between traps of this type against the same alarmActiveModelPointer and alarmActiveResourceId. When traps are throttled, they are dropped, not queued for sending at a future time.
A management application should periodically check the value of alarmActiveLastChanged to detect any missed alarmClearState notification-events, e.g., due to throttling or transmission loss.
What is alarmClearState?
This notification (trap) is generated when an alarm condition is cleared on a managed device for a specific resource and alarm type. The agent throttles generation to prevent flooding (minimum two-second gap between identical trap types). Operators receive this to know when previously reported problems have been resolved and can mark service incidents as closed.
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> '' ALARM-MIB::alarmClearState snmptrap -v2c -c public <manager> '' 1.3.6.1.2.1.118.0.3
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:
