Configuring Hardware - System Monitor
One of the most critical and important aspects of your Gentoo Linux system is a system monitor. This is a piece of software that can display the processes consuming your CPU and memory resources, network bandwidth and port traffic, disk space utilization, temperature and hardware sensors, and more. A popular system monitor is called conky. Before performing the emerge, be sure to check your USE flags. The ipv6 USE flag can cause problems with conky, so make sure it is disabled.
$ sudo emerge -av conky
Conky is highly configurable. Here is an example .conkyrc file showing most of what's mentioned above. This file should be located in your home directory.

Feel free to use this conky icon from trailer park boys if you create a Launcher for conky.
