Internet routing table "completeness" monitoring?

Has anyone put in place a method to identify if one their BGP peers
suddenly withdraws X% of their prefixes?
e.g I should expect ~420k prefixes in a "complete" routing table from
a transit peer today. If suddenly I'm only getting 390k prefixes I'd
guess a major network was depeered or similiar.
If so how are people doing this? SNMP MIB, screen scrape?
 Varying levels of completeless apply.
