title: How to know each TAB data usage in Chrome?
body: <p>Is it possible to know the data/bandwidth usage of each tab opened ?. Is there any API for this ?.  </p>
  
  <p>I want to make a chrome extension based on this. Any pointers would be helpful.</p>
  
  <p>What I exactly want to do is:
  Show a small counter beside the tab name/page title.
  The counter should update itself every 5-10 seconds. 
  It should show the amount of data/bandwidth consumed by the tab.</p>
  
  <p>chrome://net-internals/#export. </p>
  
  <p>This shows the overall bandwidth usage once the event starts ? Can I get this tab wise ?. Any API for this ?. </p>
  
  <p>Is this possible in Chrome ?. I found this in Firefox as an add-on(tab-data).<br>
