Be cautious not to rely on a show ip bgp sum many IOS versions (I don't
remember specifically) have a bug that makes that number inaccurate.=20
Most of the tools I have seen have basically done a show ip bgp
collected the whole table and parsed it. I know I wrote a tool like that
when I was a wcom.
As for tracking update packets/sec vs prefixes updated/sec, one of the
juniper trace options I think flag update, gives a summary of how many
prefixes were updated.

I believe there is pointer a screen-scraper script at the route-views
web
site that might give you this and more info you are looking for. Don't
have the info right now but if you can't find it ping me and I'll dig it
up.
