This extension created specially for Argos and linux-powered computers w/ GNOME shell. This script uses power of SVG to draw charts.
As you see at screenshot, CPU chart has 3 colors: green for iowait consumption, dark grey for user comsumption, and light gray for overall CPU consumption.
Please note that the CPU consumption is approximate. It calculates by /proc/stat output, also as memory by free, temperature by /sys/class/thermal/thermal_zone0/temp and disks by df outputs.
Different configurations of top utility doesn't allow to show processes list (see opened issue here).
To fix this, open script in text editor and replace $9 / 2 to $7 / 2. Also you may need to change head -n 10 to head -n 13. Also, you may need to change number of CPU cores (2, 4).
In further releases I will fix this by more elegant way.
