similar to: CPU Usage when idle

Hi, I have quite a few low-end development/test servers running continuously and I would like to better manage their power consumption. I have found interesting information on how to perform CPU scaling (e.g. [1] or [2]). But I cannot find if there is a way to (software) monitor power consumption on CentOS (or other such data like CPU temperature, fan speed etc.). What I read so far is that

Hello everyone, Let say 5.4 goes out today; If I fully update (today) my 5.2 system...will it be equivalent to 5.4 (all RPM packages with same version/release number?)? Or is it possible for the new point release to include NEW packages that weren't on the base relase (in this case CentOS 5)? Thanks, Jorge

Hi, I need to upgrade a system running 4.1 to 4.2, but before I do I want to list out all the packages that will be updated/installed/removed. I can run up2date -l to get a list of updates but does that show packages that need to be installed and removed as well or just the updates? Second, how would I go about upgrading 4.1 to 4.2 instead of 4.8 (i.e. latest update). Unfortunately I don't

Hello guys, I have a couple of servers that I'm about to virtualize to our VMware Vsphere ecosystem. For Linux servers I read that one needs to use the stand-alone converter (which is a live-cd that you boot from it and then you point it to your destination ESX). I would like to know from folks that have already done so...what was your experience like? Did everything went smooth? Any

Greetings- I'm running some USB DAHDI hardware on a system with a tickless kernel. The audio quality is quite poor. Could the tickless kernel be to blame? If so, when recompiling a kernel that is *not* tickless, is there a recommended KERNEL_HZ value? IIRC, older kernels used to be 1000, but newer ones are 250. Thoughts? --Tim

hello tincers, when I on battery on my notebook, running powertop, I get nic:<tinc-net-name> as the most power consuption resource in my notebook just after the screen. This happens no matter if I have traffic or not. I am not really sure that if this is really a tinc fault or a tap/tun implementation that never sleeps. any advice? -------------- next part -------------- An HTML

A new pvops kernel (78b55f90e72348e231092dbe3e50ac7414b9e1af) needs around 25% cpu while being idle with 32 guest domains in event and ksoftirq kernel threads: | root 4 3.6 0.0 0 0 ? S 21:08 0:26 [ksoftirqd/0] | root 7 8.6 0.0 0 0 ? S 21:08 1:03 [ksoftirqd/1] | root 10 0.0 0.0 0 0 ? S 21:08 0:00

Hi, all These days, I am interested in green IT area for low power OS So, I have a question about it. Is there any good idea or comments about power management related with cgroup based resource management? I have no idea about that, but it seems to be possible to find a good concept. And I hope so Is it some strange question? ^^ Regards, Dong-Jae Kang

Hi, I would have filed this as a bug but bugs.xiph.org doesn't seem to work (despite quite enthusiastically claiming to :)). So here goes: I'm seeing quite a few wakeups/sec in icecast2 2.3.2 on Debian Testing. In fact, whether icecast is doing anything or not, powertop reports 44.3 wakeups per second. This is pretty big number, on my laptop it means icecast alone is responsible for

Hello, I was not happy with the power consumption of CentOS 6 x86_64 on a new Lenovo Thinkpad x220 Tablet and I worked on reducing it. I just wanted to share with the list one of the changes which gave me the most significant improvement. As per http://www.williambrownstreet.net/blog/?p=387, add the following kernel arguments to the GRUB boot configuration: pcie_aspm=force

Hi, My laptop runs a local IMAP server so that I'm immune from breaking my mail client, and when playing around with powertop I discovered that Dovecot (in particular imap-login) wakes up every 1000ms and then every 50ms even when no clients are connected. A bit of stracing shows this: gettimeofday({1180875699, 667917}, NULL) = 0 <0.000010> poll([{fd=7,

Hi, I'm building a test asterisk server and building the latest kernel I got to wonder if there are any specific recommendations about schedulers and so forth for optimum performance. There are a few areas that raise questions in my mind and I wonder if anyone has any opinions/comments on which settings are most suitable for use with asterisk: SLAB Allocator (SLAB or SLUB?)

Hello everyone, I''ve always wondered - would dom0 be better off with a tickless kernel or not? In other words, can someone explain which choice to make with regards to CONFIG_NO_HZ? -- Stay in touch, Mark van Dijk. ,-------------------------------- ----------------------------'' Mon Aug 06 15:40 UTC 2012 Today is Pungenday, the 72nd day of Confusion in the

Hello, I have been learning Rails for several weeks now. I am working through Michael Hartl''s tutorial and other various things. My question is basically regarding what type of environment to do my development in. First, some background: I have used different linux distros on and off throughout the years, so it was easy and familiar for me to set up my desktop computer with Mint and

This may be a stupid question - but why does ssh-agent fork off a child and then exec the subcommand in the *parent* process? It forces the agent in the child process to poll the parent, so it can exit when the parent finishes. If the agent was the parent process, it could use wait() instead. I'm sure there's some reason. It'd be nice to take ssh-agent off the list of polling

I see Intel has released a new tool. Oh, it requires some patches to the kernel to record latency times. Good thing people don''t mind patching their kernels, eh? So who can write the equivalent latencytop.d the fastest? ;-) http://www.latencytop.org/ -- cburgess at qnx.com

Dear All >From my previous posts , I learned from you to make use of 'sort' , 'grep' , and 'grep -v' to manipulate text files . At now, I have generated a large text file from my autoexpect script. To be more specific, I need to find how many distinct records are there in say column#1? How can I filter out the distinct records with number of occurances less than a
