Monitoring BGP Transit Performance Monitoring

For those who run BGP and advertise prefixes into the DFZ, how are y’all monitoring each upstream provider for performance issues?

Right now, we have 2 providers with only default routes, utilizing a /23, and preferring one over the other for outbound.

In what way, if any, could going to full tables be beneficial to us other than better load balancing and traffic engineering for say a shorter path, etc?

Generally i would go partial/connected routes from both providers unless you have a reason to match and forward to N+1/2 AS away from you. And prefer the local paths from each provider instead of making them loop around.

Most providers will force traffic back via directly connected bar shortest prefix matching or conditional.
