help in monitoring performance problem!!!

Posted by Anonymous Coward | Posted in Linux | Posted on 31-01-2010

hello,

i’m having some performance problem on one of my linux machines and i hope someone will be able to help me analyzing the problem.

machine info:
linux fedora, cpu x 4 cores of 1.6Ghz, 8G memory, 8G swap.

i’ve enabled sar on my machine and created a graph using ksar utility for the last week.

the sar -A command actually monitored everything on my machine.
now, i’m trying to understand what was the problem:)

my problem was that on 2 days at that week my application hanges and we had to restart the machine in order to solve this.
now, i’m trying to understand its its i/o problem due which related to my disk, or perhaps memory problem.

the problem occured at 15:00PM on one of the days i’ve monitored. i will write down the resluts:

Code:

CPU monitor: (0.0 - 30.0)
  cpu used: 17%.
context: (0-31,000)
  cswch/s: 17,000
i/o:
  transerf/s (0- 5000) : 3000
  block read/write (0-300,000) : 100,000
  read/write/s (0 - 4000) : 1500
memory:
  memused: 7.8G (97%)
memory misc:
  buffers: (0-700m) : 200m
  cached: (0-7.5G): 7G
swap:
  swapfree: 8G
  swapused: 40kb
 
load:
  runq-sz (0-3): 2.5
  plist-sz(0-400): 350
  load average (0-40) : 30
 
page:
  frmpg/s((-)1000 - 1000) : (-)1000
  bugpg/s: ((-)150 - 150): 50
  campg/s ((-)1000 - 1000): 1000
 
paging:
  pgpgin/pgpgout  /s (0-80,000) : 30,000
  fault/majflt / s (0-55,000) : 1000
 
processes:
  proc/s (0-60.00): 1


i hope it was clear:(
i can see there is not enough memory cause he used almost all the memory, and the runq-sz is high so a lot of process running/waiting to run i think, so perhaps it might indicate the problem?

please help…:(

No, really. As trollish and dumb as they may seem, you still get such reactions. And the problem is that they may damage Free Software more now than ten years ago, when almost nobody knew what Free Software is anyway, so here are a few recent facts. http://stop.zona-m.net/node/87

Hitting the Debian Lenny sweet spot

During much of the time I was running Ubuntu, I told myself that I’d be running Debian instead, if only I could get everything working. I have tried the Ubuntu Lucid Alpha 2 build, and I still appreciate so many things working out of the box on my 2002-03-era Toshiba Satellite 1100-S101 laptop. Even the USB Headphone Set sound module I’ve been using was able to play system sounds and Flash audio in Ubuntu. However, I recently was able to get that sound module to work in Debian Lenny. All I had to do was plug it into a different USB port on the Toshiba, and now it’s working fine.

This week at LWN: RawTherapee: the newest open source raw photo editor

Posted by jfeedor | Posted in OpenSource | Posted on 31-01-2010

Gábor Horváth has been developing the raw photo converter RawTherapee single-handedly, on Linux and Windows, since 2006. The application has been freeware the entire time, with Horváth accepting Paypal donations through the project’s web site. Consequently, although there are significant changes in the 3.0 alpha release announced on January 4th, it was arguably bigger news that the project was switching to the GPLv3.

Well, it was bad enough when X@FOSDEM became a one day event (where for the past several years it has been a highly-populated two-day conference) at the upcoming Free Open Source Developers’ European Meeting (FOSDEM) taking place in Brussels next weekend, but now it’s not even a one day event. X@FOSDEM has just been sliced down to now just be a half-day conference… Well, five hours.

Windows 8, Windows Server 2012, and Office 2012: Estimated RTM Dates Surface on an MSDN Blog

Chris Green, a Microsoft employee who appears to use his MSDN blog here-and-there, posted a rather telling product support lifecycle update on December 2, 2009. In it, he details not only the public information found on Microsoft’s product support lifecycle site, but he boldly goes where no one has gone before by mentioning not only Windows 8, but Windows Server “2012? (Windows 8 Server) and Office “2012? (Office 15)… with dates.

The book aims to be a book for PHP application developers who want to improve their user interfaces through jQuery’s capabilities and responsiveness. I really think the author has done a great job at achieving this goal. The code examples are very practical which can be used inside loads of websites. You don’t especially need to be familiar with jQuery, since the book will provide you with numerous practical examples on how to improve your application. Through the code, you’ll learn some great jQuery too!
