This is not what the post was talking about though, if you have a service that truly is being fired 1000 things a millisecond, I can almost guarantee you have other metrics already up, and thus won't need anything else.
I work with realtime graphics. Thousands of things are indeed happening every millisecond and I sure wouldn't want a new hire blindly instrumenting those things just to "see if they happen." There are appropriate tools to measure performance at this granularity.
