wmalms monitors data obtained from a sensor chip: temperature, fan speed, and voltage.
It can be used as a dockable/swallowed applet with Window Maker, BlackBox and clones (incl. FluxBox), or any window manager that supports swallowing, including gnome, kde(kpanel)-1, fvwm and clones.
Alternatively, you can run wmalms as a normal window with any window manager
wmalms is designed to suit any hardware supported by lm_sensors.
It provides a wide range of customized features, including window appearance, order and representation of sensor data, refresh frequency, alarm mode, etc.
I started developing wmalms, after I tried several other sensor monitors, and neither worked for me.
