Could not find the flow monitor until I read that you had to "blindly" click the in/out figures.
Had to play with Firefox/Noscript to get the popup.
I get a screen of data that lasts for a few seconds and then is replaced with a new screen. It is not possible to "grasp" the data before it is gone.
Is this the concept? You have to know what you are looking for?
Thinking there should be some autoscroll or a freeze button?
(Not exactly what I envisioned when reading about the feature)
