WMgMon is a generic monitor applet for WindowMaker and Afterstep. It can display CPU, I/O, memory, and swap usage, as WMMon does. It can also display the result of other programs, as WMScript does. The result can be displayed as a gauge, a histogram, a percentage, a number, or any combination of those. WMgMon's advantage is that it lets you configure what's displayed in its configuration file so that you can tailor it to your preferences and easily extend it by adding new monitoring functions and new scripts.
Gnetload is a GNOME applet showing the network load of a specified network interface in a histogram. It is highly configurable; configuration options include different colors for incoming and outgoing traffic, fixed or dynamic histogram scaling, and textual representation of the current network load.
wmmclient is a small Window Maker dock applet that connects to a specified MasqDialer server and prints out status information of the current dialup connection, if there is one. Its appearance is similar to the wmppp applet. Two buttons allow you to connect/disconnect to/from the specified mserver. LEDs tell you if you are connected to the mserver and if there's an active dialup connection. If supported by the mserver, the applet will print out some load information.
