Looking at this a bit further, would this work:
- Receive trap from device
- trap sets status of interface
- Configure alert using interface status on BASIC alert manager (remember that ?? )
My thinking is that basic alert manager alerts instantly and is not dependent on database polls. I can't use custom properties, however can choose from a list of monitored interfaces rather thank having to parse for a message pattern?
I guess a key question here is what the long term plan for basic alert manager will be? If it's days are well and truly numbered this will be a non-starter...
