WMMon monitors the realtime CPU load as well the average
system load and gives you some nice additional features too...
WMMon currently provides:
* Realtime CPU 'stress' meter;
* Average systemload, like xload & wmavgload (autoscaling);
* Realtime Disk I/O 'stress' meter;
* Average Disk I/O load graphic (autoscaling);
* Realtime total Mem & Swap usage meters;
* System uptime display;
* Realtime cycling through all monitor modes;
* Can be started multiple times;
* Commandline options for help (-h), version (-v),
start mode (-i & -s) and display (-d);
WMMon can lauch 3 user definable commands for left, middle and
right mouse button clicks, which you can define in ~/.wmmonrc:
left: mycommand-1 &
middle: mycommand-2 &
right: mycommand-3 &
