Youtube Live Viewers?

Hello all, I recently started experimenting with youtube's live broadcasting feature and find it to be pretty cool. However, I can't seem to find a way to track my live viewers. I can see live views at the time the broadcast is live, but I can't find where it says how many viewers I had total for that broadcast. Am I not looking in the right place or does youtube not have this function? If not, how can I best estimate total live viewers for a broadcast? Any help would be appreciated.
