I noticed when having some trouble with code I was testing that the CPU was becoming exhausted and I would have to reboot. After rebooting a couple times I decided to check for other problems before trying my code again. That's when I noticed that the CPU with the idle process was through the roof:
I wanted to use lsof on the process, but apparently that is not an option with kFreeBSD. I tried using sockstat, but it seemed that no parameters I tried worked. I tried searching online, but all the documentation seemed to be for FreeBSD and not kFreeBSD. The man page didn't seem to be much help either.
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-
11:46:52 %usr %sys %wio %idle

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?

cpu - A tool for user and group administration
SYNOPSIS
cpu [OPTIONS]
DESCRIPTION
CPU is a tool for user administration, that was initially based on FreeBSD's pw(8). This tool will allow you to administer users and groups
on several different backends currently including LDAP and flat files. Please see the website http://cpu.sourceforge.net for more informa-
tion, or help improve the man page.
OPTIONS
There are two kinds of options; options for CPU and options for CPU modules. There are only four options for CPU, they are as follows:
-C configfile, --config configfile
The configuration file to be used by CPU. The options in this file are used for CPU modules.
-h, --help
Display help for CPU. If specified in conjunction with the -m option the help for that particular module is displayed.
-M method, --method=method
This is the method of administration. Current options are ldap or passwd (passwd is not yet working). This can be specified in the
configuration file.
-V, --version
