I use and app that displays the live down/up speed on the dock icon. I would actually like to view and retrieve the live up/down speeds so I can use it in an app I'm making. I looked in Activity Monitor and Network Utility. Activity Monitor displays the PID and received/sent packets which is good for what I want to do but that's only half the data I need. Where can I find the live streaming up/down speeds? Ultimately what I need is to know how to request/parse that live data so I can use it in an app.
