my linux bos red hat Ent 5.0 is reporting CPU usage 100% for the service/agent cimserver.basically is slows down my system and I have to kill it so my system is OK again.my question is Can I set the CPU usage for this service? I mean can I set it to use only 4% or 10% of my CPU? or any other way to troubleshoot this 100% CPU usage. Since I've uninstalled and reinstall the agent and same issue.is it possible to set the CPU Usage?

I was trying to get the status of memory usage and disk usage using sigar in windows and ubuntu. done this in windows by just copying the sigar library into jdk library. But i was unable to do so in ubuntu. I've copied the library to java-6-sun library but still can't run the program.

I've had a stable system for a couple of years now, and it just ran out of space. I cleaned some files up to get the system workable again, but can't find the big usage area, and I'm getting conflicting results.For example, when I do a df it says I'm using 44GB out of 58 GB:
Code:

I am running Server 10. I have a requirement to perform an action before the MySQL service starts, and perform another action after MySQL service stops.
I found the init script for MySQL under /etc/init/mysql.conf. I added my thing to the pre-start script there and works fine.
I am having trouble finding the script that stops the server so I can modify.
i can smb in centos 5 and i run service smb restart, it shows :smb: unrecognized service..... i run rpm -qa |grep samba,it shows

The "free" command shows that 7019 MB of memory are actually in use by my system, but when summing up the actual usage (or even virtual usage like the example below) it doesn't add up - the sum is far less than what is reported by "free":

Upon having lots of trouble with runtime.exec, i decided to bypass the top/ps command call and just get the information straight from /proc/*pid*/whatever.Now i can pull back any information from any of the files I want, and the current way i determine the CPU usage of a process is as follows:Add the UTime and STime of that process from /proc/pid/stat then divide my pidCpu by UTime + STime + NTime from /proc/stat, then multiply that by 100, should give me the % cpu usage a process is using, right?Theory being if I get the jiffies assigned to my process, I can divide that by the total jiffies the cpu assigns.

I am running Slackware 13.0. I am aware of free -m, vmstat, top, etc. However, none of these programs display how much ram each program is using. Is there a program that displays how much ram each program is using? I run a headless so I'd need a program that runs in CLI.
I know that top command shows %MEM (only two programs were using 0.1%MEM) but after running free -m I only have a total of 400 MB ram left out of my 1.5 GB of ram. Where is all that lost ram?
Does top command find out cpu time and process time for an interval and then calculates the process's cpu usage
eg: process time(interval 5sec)/cpu time (interval 5 sec)*100 %

Linux: Is there something similar to "top" for I/O?
I am trying to do some CPU intensive operation on a Linux machine and it is showing very high load.

I'm writing a shell script which aims to create a safe gtared (xxx.sql.gz) copy of MySQL databases.This script is planned to be Cron-Jobed.
Well, what I need to add to this shell, is something that limit CPU usage for the whole process (just in case if the database being generating is a huge one.)So, after few time of googling I found couple of solutions:
- Using cpulimit.
I tried to place the code in Position(1) and Position(2) but it didn't seem to be working fine.. Any idea about the right use?
And the other Solution is:- Using nice.
Well, assuming I named my shell script (sqlbacker)..
Finally, this is my first time I ever write a shell, so correct me if somewhere I made a mistake :-)
(The script itself works perfectly)
I think To get the full value from your ram on windows you need to have a 64bit install version installed, can someone tell me if its the same with linux or Unix. I have 9gb of ram on my PC & wanted to know if I it matters if I use a 32bit Distro or if I need a 64bit on my 64bit PC to utilize all the ram.

At the moment with some live linux distributions I run "free -m", on the terminal of the graphical dektop environment, without running any other command or application. Is "free -m" the rightest way to evaluate the amount of all the available ram memory left by a linux distribution? Which are the values to sum to evaluate all the available ram memory for the operating system?

I have a question. I want to monitor
- CPU usage daily
- RAM usage daily
- Harddisk Space
- top processes
- hardware failure
What commands do I need to run to output the result to a log file? I know there are solutions both paid and free, but my company does not allow. they want linux built in commands or methods to do it. I do not know bash scripting. I know some commands like "df -h" to monitor harddisk space but not sure on the other stuffs.

View 11 Replies View RelatedThere's a disfunctional process eating copious cpu time.Is there a way to effectively assign it a high nice value? I need to do this whenever it runs, for whatever reason, and I can't be bothered to track down all the scripts and scenarios that cause it to run and change the script to use nice. And I can't be bothered to manually run renice whenever I notice that it's running.
I want the OS to automatically assign a high nice value to this process, perhaps based on the processes name. Is this possible?Presumably, a cron job could run every 5 minutes and run "renice" on every process matching a given name, but I'm hoping for a solution with more finess.
Trying to delete injected code (one line) into multiple .php and .html files of a server with sed command but it seems there is a problem with sed when " and / are included in the string to be deleted.The string that needs to be deleted is <img heigth="1" width="1" border="0" src="http://imgddd.net/t.php?id=16382836"> However the last part of the string (id=########) is not constant (the number is variable) so I used the following:find /home -type f -iname index.html* -o -iname index.php* -o -iname index.html* -o -iname index**| while read FILE; do sed -i "s|<img heigth="1" width="1" border="0" rc="http:\imgddd.net*">||g" "${FILE}"; doneFor some reason it successfuly deleted the injection on .html files but NOT in .php files

So a few weeks ago a Linux server was having high CPU usage, but we weren't able to determine what program was causing it. The top and ps commands (and others) didn't show any programs using a huge amount of CPU resources, but %idle was at 0 and our monitoring software showed 100% usage. Yet no process was found by ps and top to explain it. The usage was caused by a DBA doing some work, but we never found out why we could not see the application causing the usage.
Now here I am several weeks later and I have the same problem, but this time it is on my Palm Pre. I upgraded to 1.2.1, and now it runs very slowly.
A quick top in an SSH session shows:
Code:
Now, assuming I'm not just being stupid (which is always a possibility) the first two values on the CPU line show a total of 100% usage, yet no process shows that. The ps command shows a similar result.
So, what is causing the high CPU usage? Why doesn't top and ps show it?
