Measure your system load in Ubuntu 12.04 via the handy appindicator System Load Indicator
System Load Indicator is a handy tool that displays various system informations on the Unity panel, making them easily perceivable via vividly colored filled squares.
By default, System Load Indicator exposes the processor and the memory usages, "mode" that can be enriched by selecting Network, Swap Space, Load and Harddisk under
System Load Indicator/Indicator Multiload appindicator-->Preferences-->Monitored Resources-->check the desired items
The indicator comes with a decent tweaking availability, consequently, users can adjust the colors used to represent the amount of usage per "tracked" item (like for instance, changing the cached memory's color to red as opposed to the used memory's to green, in order to trigger an "abrupt" contrast) as well as the width of the "boxes" in which the indicators run.

sudo add-apt-repository ppa:indicator-multiload/stable-daily
