I'd also be careful to avoid vanity metrics. I think your time is better spent building a dashboard for actionable metrics. A map of all of your api calls might look cool but what are you going to do with that? I'm more interested in average customer life-time value, churn, customer acquisition cost, retention etc... I've been looking into using geckoboard for this as it seems like it would make setup go much faster.

If you suddenly see a huge cluster of API calls in a single geographic area, that might point to an issue, such as a problem connecting to the local CDN. The stuff you're talking about is actionable from a business standpoint, but the stuff in the article is meant to be actionable from a performance and problem resolution standpoint.

What are you going to do with that? Diagnose problems when things start flipping out, obviously.

Sprinkle the stat-recording somewhere common to all the calls (metaprogrammy-inheritance-whatever) and it's not even like it's a ton of work.
