BGP neighbor Monitoring using SNMP Traps

Is anyone using SNMP Traps for monitoring BGP neighbor status?

I have a need to use traps as BGP discovery/polling is not supported on devices that I am monitoring especially as they are using VRF's.

I do however get SNMP traps for BGPpeer status of 'idle' and 'Established' using Trap types BGP4-MIB:bgpBackwardTransNotification and  BGP4-MIB:bgpEstablishedNotification.

The problem I have is how to use these traps to create state based alerts. By that I mean when a BGPPeer goes 'idle' I get and alert and when it becomes 'Established' the alert is reset.

The stumbling block appears to be that when Traps are used to create alerts it is done on a Node basis, hence with multiple BGPPeers on a single node, I can only ever have one active alert per alert definition per node.

So for example

BGPPeer x.x.x.x goes idle on Node A, and an Alert is raised for Node A  - (so far so good)

then

BGPPeer y.y.y.y. goes idle on Node A, and no Alert is raised for Node A as it is already an Active Alert from above.

Any suggestions how this can be achieved

Thanks
