WMCPULoad is a program to monitor CPU usage. It is a dockapp that is supported by X window managers such as Window Maker, AfterStep, BlackBox, and Enlightenment. It dispalys the current usage, expressed as a percentile and a chart, and has an LCD look-alike user interface. The back light may be turned on/off by clicking the mouse button over the application. If the CPU usage hits a certain threshold, an alarm-mode will alert you by turning the back light on.
WMLmMon is a system health monitoring applet for WindowMaker, which uses a kernel module to read the status of lm78/75 chips on most current motherboards. WMLmMon displays current CPU and motherboard temperature on systems equipped with such sensors. It has been successfully tested on the Supermicro p6dls board.
