Just to clarify this:
For all alert types below BGPmon.net sends out an alert within minutes:
1) prefix withdrawal (prefix disappeared)
2) new upstream
3) new prefix
4) origin AS changes
5) ASpath regex failure
6) policy violation
7) RPKI validation failure

There's one other feature, the routing-report feature, that runs only 
once a day. It's similar as the cidr report, but specific to your AS. I 
like to refer to it as a rancid for your BGP announcements.

It's basically a diff between how your routes were visible today and 
yesterday. This specific feature will also notify the user if you lost / 
gained one or more upstreams per prefix.
Also see http://bgpmon.net/blog/?p=257 for more information about that 
specific feature.

Cheers,
  Andree
