It requires libdockapp. wmfire can monitor the average cpu load, or individual cpu load on SMP computers. Additionally it can monitor the memory, network load, or just be set to show a pretty flame. On entering the dock a burning spot replaces the cursor, and after two seconds symbols to represent the current monitor are "burnt" onscreen wmforkplop wmforkplop is yet another dockapp for WindowMaker, or any windowmanager/desktop environment that handles dockapps (KDE has a dockbar extension, and gnome swallows). It is a mixture between wmhdplop and the great wmtop: wmforkplop monitors your processes by sending visual stimuli to your cortex each time your kernel forks or kills a process. WMgMon a generic monitor applet for WindowMaker and Afterstep. It can display system info, the result of other programs, etc. and can be configured to display them as a gauge, a histogram, a percentage, a number, or any combination of those wmmemload wmmemload is a simple dockapp for WindowMaker on X Windows that displays memory and swap space usage. It is very heavily based on WMMemMon and WMCPULoad. WMMemMon WMMemMon is a mem/swap monitor dockapp for WindowMaker, AfterStep and BlackBox. Outside circle is Mem usage in percent,inside is swap. wmSMPmon wmSMPmon is a Window Maker applet for monitoring the CPUs of SMP systems (in french).
