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.
wmnet polls network statistics and does a few things with the data it gets. It has small blinking lights for the rx and tx of ip packets, a digital speedometer of your tcp/ip stack's current speed and neatest of all, a bar graph like xload et. al which has a tx speed graph from bottom-up and rx speed graph from the top-down. The speedometer keeps track of the current speed per second and shows it in a color corresponding to which of rx or tx that has the highest speed at the moment.
