For those missing network applet. (This applies to Cinnamon- Fedora 17- 32 Bit and to default internet connection p17p1)
Go to Cinnamon setting>applets>Get New Applets.
Download Network Usage Monitor applet and extract contents to /home/user/.local/share/cinnamon/applets/
logout/login & activate applet by again going to Cinnamon setting>applets
Install vnstat by
sudo yum install vnstat
edit file applet.js by
sudo gedit /email@example.com/applet.js
replace etho by p17p1 and save.
open gnome-session-properties by alt+f2 and type gnome-session-properties
create a new property say named vnstat with command sudo systemctl start vnstat
logout/login and you have your network Usage Monitor nicely sitting at bottom panel and giving you internet data statistics.
I think last instruction of adding it to gnome-session-properties was not necessary. Instead change eth0 to p17p1 in /etc/vnstat.conf
