Those are the Node web-kit Developer tools not Construct 2 tools. C2 does not export the bug hunter thing. You need to make your own text object and add the debugging information with expressions. There is cpu,fps,and every object has an item count, along with other useful things.
Look up append text, newline, and expressions. A simple FPS counter would look something like this:
System.Every 60*dt Seconds |----------->|TextObject.Set text="fps" |
