WMCPULoad - A dockapp to monitor CPU usage
|
||
|
|
|
||
|
|
General Information
|
||
|
|
===================
|
||
|
|
WMCPULoad is a program to monitor CPU usage. It is a dockapp that is supported
|
||
|
|
by X window managers such as Window Maker, AfterStep, BlackBox, and
|
||
|
|
Enlightenment.
|
||
|
|
|
||
|
|
It displays the current usage, expressed as a percentile and a chart, and has an
|
||
|
|
LCD look-alike user interface. The back-light may be turned on/off by clicking
|
||
|
|
the mouse button over the application. If the CPU usage hits a certain
|
||
|
|
threshold, an alarm-mode will alert you by turning back-light on.
|
||
|
|
|
||
|
|
It runs on GNU/Linux / FreeBSD / OpenBSD / NetBSD / BSDi / Solaris / Cygwin.

Frequently Asked Questions
|
||
|
|
==========================
|
||
|
|
|
||
|
|
Q) Which window managers do support dockapps?
|
||
|
|
A) - Window Maker http://www.windowmaker.org/
|
||
|
|
- AfterStep http://www.afterstep.org/
|
||
|
|
- Blackbox http://blackbox.alug.org/
|
||
|
|
- Enlightenment http://www.enlightenment.org/
|
||
|
|
- Fluxbox http://fluxbox.sourceforge.net/
|
||
|
|
- Waimea http://waimea.sourceforge.net/

||
|
|
- PWM http://www.students.tut.fi/~tuomov/pwm/
|
||
|
|
- Golem http://golem.sourceforge.net/
|
||
|
|
|
||
|
|
Q) Can I set the initial size?
|
||
|
|
A) No. As far as I know, there is no dockapp which can be set the size.
|
||
|
|
|
||
|
|
Q) (How) Does WMCPULoad support SMP system?
|
||
|
|
A) WMCPULoad will probably work fine on an SMP system. However, it only displays
|
||
|
|
the usage statistics for the all CPUs. I may add the new command line option
|
||
|
|
(e.g. '--cpu <number>') to specify the CPU number. but this feature is the
|
||
|
|
bottom of my TODO list, since I do not have an SMP system.
|
||
|
|
-----------------------------------------------------------------------------
|
||
|
|
NOTE: WMCPULoad has '-c, --cpu' option since version 0.8.0. but it only works
|
||
|
|
on GNU/Linux. (Thanks to Laurent Raufaste for beta test)

|
|
Q) Why is kamp-idled spending many CPU time on my GNU/Linux box?
|
||
|
|
A) kapm-idled executes HLT instructions to save power.
|
||
|
|
|
||
|
|
Stephen Rothwell (GNU/Linux APM maintainer) said:
|
||
|
|
"kapm-idled may do quite a lot more than just execute HLT instructions
|
||
|
|
depending on how smart the BIOS is about saving power. Unfortunately, some
|
||
|
|
BIOSs are pretty dumb and in some cases more power is consumed by having
|
||
|
|
CONFIG_APM_CPU_IDLE defined in your kernel build than by not."
|
||
|
|
-- from debian-devel mailing lists
|
||
|
|
|
||
|
|
'-p, --ignore-proc' option will help you. (e.g., wmcpuload -p kapm-idled)
