Operating Systems AIX Problem with nmon, actual CPU usage per process Post 302779107 by zaxxon on Tuesday 12th of March 2013 06:19:54 AM

Thanks, but the options I used are valid switches I get displayed when I issue an nmon -h or if I check the man page, as well in the documentation in the IBM Wiki.

Thanks, but tprof is for monitoring a program that you start, like sleep. I have processes that are running already and I have to check them for let's say an interval of 10 seconds and have to get their actual CPU usage for exactly this interval.
I don't want it since the process is alive (that would be regular ps) nor do I have the option to start a program.
For the explanation of -f together with -c and -s for nmon it seems to be a pity that this option is valid as it looks to me, that the output file is being written and does not get any addition 5 or 10 seconds later.
But I got your point and I think I have tried that already. I will have another look into it, but iirc, the values I got back were not that what I was looking for.


The background of all this is that I am about to write a plugin for Nagios which shall just capture the the actual CPU usage of the specified interval for a process.
Those plugins I have found do usually issue a ps and work with values that are the average since the process came to life.
When this is several days and you currently have a workload peak, you get for example just 12% CPU usage back while it is actually 77%.
So this approach is in my eyes "useless".

Maybe I explained it better now. If you have any other ideas, let me know. Thanks a lot so far for your efforts both.

wmbubble

WMBUBBLE(1x)															      WMBUBBLE(1x)

NAME

       wmbubble - system load monitor

SYNOPSIS

       wmbubble [options] [program1] [program2]

DESCRIPTION

       This  manual  page  documents briefly the wmbubble command.  This manual page was written for the Debian GNU/Linux distribution because the
       original program does not have a manual page.

       wmbubble is a dockapp-style CPU, memory, swap and load average monitor.	Based on the GNOME BubbleMon applet, this program has been consid-
       erably improved.

       The  higher  the  water level, the more memory is in use. The more profuse the bubbles, the higher the CPU usage. There is also a real-time
       CPU percentage display.

       When the mouse is moved into the window, the display will change to show the load history, or, if the right shift is held, the current mem-
       ory  usage.  If	you press the right mouse button, the window will freeze in that state. You can unfreeze the display by pressing the right
       mouse button again.

       program1 and program2 are the programs to spawn when either the left or middle mouse button is pressed, respectively.

OPTIONS

       -d     disable swimming duck

       -u     disable upside-down duck

       -c     disable CPU meter

       -m     disable memory screen

       -p     use alternative color scheme in memory info screen

       -k     display memory and swap statistics in megabytes

       -h     display help

AUTHOR

       wmbubble was written by timecop <timecop@japan.co.jp>

       This manual page was written by John H. Robinson, IV <jaqque@debian.org>, for the Debian GNU/Linux system (but may be used by others).
