Colin Ian King just tweeted about eventstat. But his tweets are protected, so you have to login to Twitter and Follow him in order to see them.

Eventstat periodically dumps out the current kernel event state. It keeps track of current events and outputs the change in events on each output update. The tool requires sudo to run since it needs to write to /proc/timer_stats to start and stop the event monitoring.

Maybe there’ll be a blog post on it shortly, as well.
