If you've ever wanted to know what's happening with your web site as it's happening, you may want to take a look at real-time web site analytics provider Chartbeat. It's a new and very slick service that provides a rich set of real-time analytics. They offer a range of useful tools like their Real-time Dashboard (shown below), traffic alerts (ex: get an email if you've got an above average burst of site visitors), and their API (our chartbeat API Profile).
