CPU usage of a process
I'm trying to monitor the CPU usage of a process and output that value to a file or variable. I know topas or nmon can tell me this in interactive mode but what I need is topas-looking output that allows me to write to a file after a discrete interval. Unlike nmon data collection to a file on top processes I want to see the CPU consumption of the process no matter what it is.
Anymore know of a method to do this? I've been searching the web and forums but haven't had luck finding anything yet.

Hi,
I am designing a load balancer for an application. I am trying to find out the CPU usage by a specifc Unix process (PID is known). I guess I can use ps command to find that. can somebody help me in finding what exact command I should use to find? It is on AIX 5.3.

Hi,
I have a shell script. But, upon execution of the same, the cpu usage is sometimes getting 100 % (checked executing top command).
At that point of time, my process hangs, doesn't run anymore. I need to kill it manually.
My concern is, is there any default method, by which I can check... (1 Reply)

wmforkplop
WMFORKPLOP(1) User Commands WMFORKPLOP(1)
NAME
wmforkplop - Monitors forking activity and displays top CPU consuming processes.
SYNOPSIS
wmforkplop [options]
DESCRIPTION
wmforkplop is a program that monitors the forking activity of the kernel and displays a list of the most CPU-consuming processes. Although
primarily aimed at Windowmaker, it will run on any window manager, either as a dockapp or as a standard X11 application.
Option list:
-h, --help
print this.
-v, --verbose
increase verbosity
-V, --version
print version
--fontpath path add a new directory to the font search directory list
default: --fontpath=/usr/share/fonts/truetype (and subdirectories)
--fontpath=/usr/share/fonts/ttf
(and subdirectories)
--fontpath=$HOME/.fonts
(and subdirectories)
--font fontname/size Set the 'small font' name/size in pixel (default: --smallfont=Vera/6 The font name are case-sensitive, and must corre-
spound to the name of a .ttf file which can be found in one of the fontpaths By default, wmforkplop tries to load the following
fonts:
* Vera/6, DejaVuSansMono/6, Andale_Mono/6, Verdana/6, Trebuchet_MS/7
-c n, --colormap=n
select colormap number n (0 <= n <= 5)
-g[=WxH+x+y], --geometry[=WxH+x+y]
start in window (i.e. undocked) mode with specified geometry (i.e -g 96x32 or -g 64x64+0+0)
--32, --48, --56
start in a reduced dockapp, for people whose dock is too small too contain 64x64 dockapps
--no-top
disable the wmtop feature, you will only see the fork animation.
--no-fork
disable the fork animation, you will only see the list of top processes.
--threshold=n
minimum CPU consumption (%) of a process listed in the top-list (default 3%)
-u n, --proc-update-delay=n
set the delay between two reads of /proc, the default is 150 (milliseconds). Setting a small value gives accurate results, but con-
sumes more CPU as reading /proc is quite expensive.
See /usr/share/doc/wmforkplop/README.gz for more details.
