SNMP inform redundancy for application failover cluster

SNMP inform redundancy for application failover cluster

I understand currently there is a nnmtrapreceiver process runs on BOTH the nodes (active and standby) in the application failover cluster. This means that, during application failover, no trap is lost. However this is not the case for SNMP inform.

This feature request is to add the same redundancy support for SNMP inform. Can we have a similar nnminformreceiver process running on both active and standby NNMi nodes to prevent the loss of inform traps during the application failover?

Dear Submitter,

Based on our assessment, the INFORM should be handled by Stand-by system once it is active and you should not lose any INFORM messages.

Please follow up with support if that is not happening.

The actual issue is that the standby system does not produce an acknowledge to the SNMP inform as the active system does, so the standby system will receive multiple retransmissions while in that state. It would be nice for the stanby system to respond with an ack, so it acknowledges the receipt of the inform and the source node doesn't have to retransmit the trap consuming unnecessary resources on the device and the standby system as well as bandwidth utilization.

Thanks. That clarifies the issue.

Yes, we do not sent ACK because there are no major services running on standby system. I would move this Idea for voting and we shall take further action on this based on interest from community.
