system monitoring applet

[Rafnews]

Hi,

i'm looking for a good system monitoring for fedora 18.
i found something about standard applet package called
"gnome-shell-extension-system-monitor-applet
rpm"

AFAIK it will be displayed on the top bar close to clock/date.

but i was think is the one displayed on the theme (
http://forum.pinguyos.com/Thread-How-to-Use-Tint2-Instead-of-Docky-in-Shell)
on the right side bar is not the same.

is there someone who know if it's the same ?
thx
