Getting CPU usage per Process of Chrome

Question

I developed a Chrome-Extension and want to know if it is possible to get CPU usage of any tab in Chrome (please see the image)? I saw a few questions which are very old. Maybe there is some new techniques to get the CPU usage for each tab.

Answer 1

It is possible. You need to request the permission: "processes" first in your manifest.json with something like:

{
  "name": "My extension...",
  ...
  "permissions": [ "processes" ],
  ...
}

If you are on dev-channel you'll have chrome.processes available. On other channels the extensions will be rejected with an error saying:

'processes' requires dev channel or newer, but this is the stable channel.
