0.2 E-monitor is a multiple monitor epplet. It features CPU, memory, swap, network monitoring functions, APM, clock and date. The philosophy is to have a lightweight monitor but still VERY configurable and lighter than gkrellm. System, user and nice usage are shown in different gradient colors. Percentage is displayed as a gradient as well.
Colors are fully customizable via a configuration window.
Refresh rate can be set. Size and orientation of the epplet are set at start-time from the configuration file that you have to edit for these settings. It allows to change the mapping of the keyboard with a simple click as Gkbd does for the Gnome panel. The configuration is however simpler. All this at run-time and via a configuration window.
