The SnmpPoller is sending the interfaceOperDown events every time a requisition is synched or a single node is rescanned.

Description

This problem is really easy to reproduce:

1) Enable the SNMP Poller on service-configuration.xml and restart OpenNMS.
2) Add some nodes to a requisition
3) Add a policy to enable the SNMP Poller on all the SNMP interfaces (for facilitate the tests).
4) Be sure that the target node meet the conditions for sending the event for at least one interface (operStatus=down + adminStatus=up)
5) Sync the requisition

After synch the requisition, you should see an interfaceOperDown event for every interface that match the condition (operStatus=down + adminStatus=up).

Every time you sync the requisition or send a forceRescan on the node in question, you are going to see the interfaceOperDown event en each interface that match the condition.

In certain occasions, the event is sent twice (which is even more weird).

Antonio has helped me to fix the problem.

Fixed on revision d9d0642039ec6aaaf3f8e37e2e49f28ec3c613b7 for 1.10

Note: If OpenNMS is restarted and the current status of the interface is down, the event is going to be sent no matter if it was sent before.

If the EnhancedLinkd is a priority now, you can work on the SnmpPoller after that.

The thing is right now, on the stable 1.10.9, the SnmpPoller is unusable because of this problem, and there are customers that depends on this.

Alejandro I'm working on EnhancedLinkd with the objective of finishing very soon. Then I have to work on snmppoller.
But let me understand how urgent is this problem....I can give it a priority on the work I'm actually doing

Antonio, please don't forget this

I have reviewed this issue with Alejandro. We should do the following:

Provisiond/Caspd should update the values of the snmpoperstatus and snmpadminstatus fields only when the snmppoll field is set to 'N' and Provisiond should be fixed to NEVER send any status events. It is not a poller.
