I used SNMP trap to monitor the status of switch interface and I observed weird behavior of SNMP trap notification. When the last SNMP trap was in OK state then the next OK state event for another interface was never triggered the alert. I saw that the SNMP trap message output was changed on Centreon monitoring portal but alert was not sent. Please help to advise me what could be the issue. Thanks so much!
Hi

Hi
I have tried “Is Volatile” option but that is only sent alert when the last and the next trap event are in Non-OK state. If the last and the next trap event are in OK state then the trap event for another interface was not triggered the alert. I am not sure if Centreon DSM can be used to resolve this issue please advise me. Thanks
With Centreon DSM, you will have a “slot” per network interface.
So if you have 2 linkdown traps on 2 different network interface, you will have 2 different alerts.
When you will receive a linkup from a linkdown, this will recover the first alert and you will keep second alert. Then when you will receive the linkup for the second interface, you will see the change.
If you enable notification for the “generic-service-passive-custom” service template uses for the “slot”, you will receive all notifications

Hi Laurent, Thanks so much for your time. I tried Centreon DSM and let you know the result.
Hi
I have the same problem as yours, did you manage to receive one ok trap after another?
I don’t understand why ‘is volatil’ only works with non-ok traps, when working with snmp alarm traps normally I need all your traps to be managed, not only non-ok state ones.
I achieved logging 2 ok state traps one after another activeting the ok stalking option in Data processing tab. But this only logs as documentation says, does not notificate.
Thank you in advance,
Sandra
Hi, ‘is volatil’ is an option to send notification, only for non-ok status, is status change or if output of the plugin change.
But for OK status, only one notification is sent.
If you want to send a notification for several OK received, you need to use Centreon DSM & slots.
Regards,
Thank you
