Chromebook network usage, is there an app for that?
 

Two things have changed in my household. I upgraded my internet speed, but in so doing agreed to a monthly cap. Second, my daughter bought a chromebook and LOVES it, especially the video chat thing.

So, is there a recommended app that will monitor the data usage of the network connections of a chromebook? I've been searching for three weeks on and off - my google-fu is weak.

thanks
