Dear fellow Mint 13 Cinnamon users,

I've just recently installed Mint 13 Cinnamon, replacing Mint 13 MATE. While I was using MATE, I was able to install a Network Monitor applet. On the lower-right of my screen, I could see how much upload and download was happening, just by seeing the colors and heights of the moving bars.

How can I get this same thing also on Cinnamon?
