I do not know kFreeBSD at all well. I do know the /proc filesystem is called procfs. So, there should be some C include file (header file) that has the structure of all of the procfs files. These are used in all of the commands like ps, top, etc.
Try this:
Code:
find /usr/include -type f -name '*proc*'

Dear All,
Our HPUX 8 GB 8CPU database server is behaving abnormally for the last 4+ weeks. I have generated a sar output and it is here-

Since yesterday the vmstat command is displaying the cpu idle time at 100%At each time interval. It never changes. Not sure what it means other than it Quit calculating that stat. And I'm curious why. Using sar I can display a correctCpu idle percent, but vmstat does not. Any ideas why or... (2 Replies)
hi,
i want to know cpu utilizatiion per process per cpu..for single processor also if multicore in linux ..to use these values in shell script to kill processes exceeding cpu utilization.ps (pcpu) command does not give exact values..top does not give persistant values..psstat,vmstat..does njot...

Hi, I checking yesterday's SAR logs for one of our servers and it was showing that utilisation was down to 0% for 10 minutes at 2am. We're unaware of any jobs running at this time so need to find out which process caused this spike.
Is there anything built into SAR (or does anything else exist)... (11 Replies)
I am using Ubuntu 9.04. I want to write a shell script to get the information about cpu idle from top command at the real time when i call it, compare cpu idle with 20 (20%), if cpu idle > 20 exit 1, vice versa exit 0. Anybody can help me to resolve it ?
Thanks alot. (7 Replies)
I need a shell script that will monitor a few conditions and not execute until the these conditions are met. The problem I'm having is that I can not perform a database snapshot (backup) of a sybaseIQ database unless the CPU Status Idle % is above 60% or the snapshot (backup) fails.
If... (2 Replies)
Hi Everybody,
Can anybody explain how CPU idle% is about 50%, but runq-sz more than 1?

linprocfs
LINPROCFS(5) BSD File Formats Manual LINPROCFS(5)NAME
linprocfs -- Linux process file system
SYNOPSIS
linproc /compat/linux/proc linprocfs rw 0 0
DESCRIPTION
The Linux process file system, or linprocfs, emulates a subset of Linux' process file system and is required for the complete operation of
some Linux binaries.
The linprocfs provides a two-level view of process space. At the highest level, processes themselves are named, according to their process
ids in decimal, with no leading zeros. There is also a special node called self which always refers to the process making the lookup
request.
Each node is a directory containing several files:
exe A reference to the vnode from which the process text was read. This can be used to gain access to the process' symbol table, or to
start another copy of the process.
mem The complete virtual memory image of the process. Only those addresses which exist in the process can be accessed. Reads and writes
to this file modify the process. Writes to the text segment remain private to the process.
Each node is owned by the process's user, and belongs to that user's primary group, except for the mem node, which belongs to the kmem group.
FILES
/compat/linux/proc The normal mount point for the linprocfs.
/compat/linux/proc/cpuinfo CPU vendor and model information in human-readable form.
/compat/linux/proc/meminfo System memory information in human-readable form.
/compat/linux/proc/pid A directory containing process information for process pid.
/compat/linux/proc/self A directory containing process information for the current process.
/compat/linux/proc/self/exe The executable image for the current process.
/compat/linux/proc/self/mem The complete virtual address space of the current process.
EXAMPLES
To mount a linprocfs file system on /compat/linux/proc:
mount -t linprocfs linproc /compat/linux/proc
SEE ALSO mount(2), unmount(2), procfs(5), pseudofs(9)HISTORY
The linprocfs first appeared in FreeBSD 4.0.
