Hi Dojo,
We recently added SNMP-Alarm forwarding to an overall SNMP-Collector and would like to suppress the sending of relatively short alarms to that system.
Just like hysteresis on alarm templates, we want to delay the alarms on DataMiner to a 3rd party system; meaning say only if an alarm lasts for 5 minutes in DataMiner, the SNMP notification should be sent to the 3rd party system.
Without touching the alarm template, is there any way to achieve this ?
(this is for first time alarms, so SNMP resend notifications isn't what I am looking for)
You could use the correlation engine to set an alarm property when the alarm is persistent for more than x minutes.
Using an alarm filter, you can then forward alarms where this property is set.
Hi Arun,
As far as I know currently it is not possible to define hysteresis on SNMP Managers.
The purpose of a SNMP Manager is to forward a trap whenever an event (in this case an alarm) is available in the system. I believe hysteresis does not fit on this feature. A possible workaround for this use case could be using alarm storm prevention:
Alarm storm prevention allows you to limit the amount of traps being forwarded to the 3rd party systems. However, it will not delay the delivery of the trap.
Thank you Miguel for the input.
Thank you Ive.
