Free simple monitor software for linux

Simple Monitor is a SuperKaramba theme inspired by the simple but effective "Very Simple Monitors" theme by the user humanthing. Some values are not displayed properly though in Very Simple Monitors (network values and IP). This could be because of different setups. My computer is pretty standard so my theme should function properly on most pcs. http://www.kde-look.org/content/show.php?content=48973
I like a tight and clean desktop, so I simplified the idea even more. This theme is showing all basic information, and nothing more.
Main features:
- Processors type
- Processor speed
- Processor load (number and graph, for one proc)
- Processor Temperature
- Amount of ram used / amount of ram
- amount of swap used / amount of swap
- amound of HDD space used / amount of HDD space total (for "/root" and "/home")
- HDD temperatue (for "/hda", I could add another drive if requested)
- Computer name
- Computer ip
- Network load (up- and download, values and graph)
- Amount of transfered data thrue internet (up- and download) since last boot
Enhancements:
- Made the three blocks clickable.
- The CPU block opens Processor information
- The Memory block opens KsysGuard (youll need to have it installed to be able open it, obviously. Its in Kubuntu by default)
- the Network block opens your computers ip settings window
- Added a line for your computers uptime
- Changed font colors to very dark gray and very light gray, instead of black and white, to make it look softer.
