Hi all, I would like to monitor the power consumption of my server. What I am looking for is: * a simple monitoring device that would measure the power consumption of 1 server * a way to get the consumption reading from that device to my centos server (via usb / wlan / whatever works) Any suggestions? Best, Peter

...' and via package 'R.cache' which uses a own filetype '.Rcache'), my R session consumes about 200 MB of RAM, which is fine. Now, when I make use of the previously cached object (i.e. loading it, assigning it to a certain field of a Reference Class object), I noticed that RAM consumption of my R process jumps to about 250 MB! a Each new loading of cached/saved objects adds to that consumption (in total, I have about 5-8 objects that are processed this way), so at some point I easily get a RAM consumption of over 2 GB where I'm only at about 200 MB of consumption when I co...

...out how to email from a worker. I decided to be a bit piggy and just inhale all of rails. Sorted. I am noticing some rather ominous behavior though. The setup: My worker takes an uploaded image as a param and passes it (via system call) to a C++ image processing engine. Take a look at these memory consumption figures for successive runs uploading the identical image each time: All figures in megabytes 343 C++ image processing idle 365 max memory consumption during 3rd C++ image processing run 318 C++ image processing idle 340 max memory consumption during 2nd C++ image processing run 290 C++ imag...

Hi WizaRds, I'd like to overplot UK fuel consumption per quarter over the course of five years. Sounds simple enough? Unless I'm missing something, the following seems very involved for what I'm trying to do. Any suggestions on simplifications? The way I did it is awkward mainly because of the first call to plot ... but isn't this n...

...uld you choose between this two and why? 2. This question is more theoretical m<-sample(c(10:20),10,replace=T) f<-sample(c(10:20),10,replace=T) t<-m+f s<-rbind(m,f,t) s Let's say I have a panel sample at disposal and consider m to be the monthly average quantity of juice consumption for the male part of the sample and f to be the monthly average quantity of juice consumption for the female part of the sample, and t the average quantity of juice consumption for the whole sample. For the mean of the whole sample i have a confidence interval of say +/-2 each month (say I hav...

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 support is quite limited in this ke...

Hello everybody! We have a interesting issue about dovecot behavior here. First, the scenario: We have 2 server running with the same load, one with our old pop3 solution (out of date) and other with Dovecot. We realized that dovecot are comsuming more CPU, and this consumption is growing day by day. When we starts dovecot, it runs between 40%-45% of CPU consumption and our old solution runs on 30-35%. This is quite acceptable, so no problem here. The problem is one day after it jumps to 45%-55% of cpu comsunption while the old pop3 solution runs on the same CPU co...

Hello, I use Asterisk 1.0.2 on a RedHat Enterprise Server 3.0 (Kernel 2.4.21) and i experienced that the memory consumption of the asterisk-process started by the init.d-script raises continously. Now, after 3 hours of operation (on our testing-system we have 30 concurrent connections to another asterisk box using IAX2 and GSM codec) there is already 66MB allocated. I think this could be ok, but the memory consumptio...

Hi All, I am working on an example where the electric utility is investigating the effect of size of household and the type of air conditioning on electricity consumption. I fit a multiple linear regression Electricity consumption=size of the house hold + air conditioning type There are 3 air conditioning types so I modeled them as a dummy variable Type A Type B Type C Where type A is the reference Below are the results Electricity consumption= 0.4 size of...

Hi Everyone, I'd like to announce a project joint between the University of Bristol and Embecosm. In this project we hope to identify what effect a broad range of compiler options has on the energy consumption of different embedded platforms. To do this we are finding a set of relevant benchmarks, compiling them with different options and measuring their energy consumption on these platforms. We originally announce this project at the GCC Cauldron (presentation here http://jpallister.com/wiki/images/4...

Hello, I'm slightly off-topic here, but it is somewhat CentOS related! I'm in search of some hardware that consumes a low amount of power for use as a test-bed for Linux, various coding projects, and LAN services. 1) Low power consumption (10-15W ... maybe 30W at most) 2) Must run Linux without too much fuss (CentOS or otherwise) 3) Must have two NICs (fast ethernet or better) 4) Memory - 1GB or better 5) Can be configurable either via serial or VGA. 6) Accepts a normal hard drive, not CF -- drive capacity is my concern. 7) spare...

R is so smart! I found that when you switch a column from integer to factor, the memory consumption goes down rather impressively. Now I'd like to learn more. How does R do this? What does R do? How do I learn more? I got to thinking: If I was really smart, I'd see that a factor with 2 levels requires only 1 bit of storage. So I'd be able to cram 8 such factors into a byte. But t...

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...

...mentation. I was using constant bit rate, when I set VAD as enabled the Delay was bigger. You told me by IRC that VAD doesn't have to do with the Delay, but it is happening to me. What could it be? 4.- Another thing you told me by IRC is to pack two frames in one packet to reduce the bandwidth consumption. I was packing just one frame per packet and it worked. I got audio in both clients but the bandwidth consumption wasn't as low as I wanted. Actually my softphone is consuming 3.5 KBytes/sec (Speex+ RTPheader). So, I try to pack two frames per packet but the audio is too bad. I call the spee...

Hi, Chris Lattner wrote: > This is fine to me in principle, but please make sure this doesn't > impact compile time or memory usage of llc somehow. OK. Any recommended way to do this? Is there some nice way to benchmark speed + memory consumption of llc in LLVM testing infra at the moment or should I just use 'top' to the inspect memory consumption and 'time' for speed measurements with a code generation from a big bitcode? -- Pekka Jääskeläinen Department of Computer Systems Tampere University of Technology, Finland ht...

Hi, I am running ClamAV process which is invoked by Cron scheduler around 3:00 AM ( Midnight) on remote server running CentOS Linux release 7.6.1810 (Core). Is there a way to measure what was the system resources consumptions like CPU, Network, I/O, Memory and Computing load is being used and is it possible to find out how much time it took to complete the scan? Any help will be highly appreciated. Thanks in Advance. Best Regards, Kaushal

CentOS 6.4, x86_64. ntpd on one of my systems has started consuming 66% of one core, although it appears to be functioning correctly otherwise. No pertinent logs. Of course, nothing was changed :) I've seen this before many times, but usually the CPU consumption falls back to normal within a day or so, but this has been going on for several weeks now. Stopping and restarting ntpd makes no difference. Reinstalling ntpd makes no difference. The ntpd.conf file is the same as on 200+ other systems, all of which work normally. Anyone seen this before? S...

Hi all, I am using lm_sensors to monitor the power consumption of a CentOS box. I notice that after upgrading from 6.5 to 6.6 the power consumption increased sharply from approx. 60 watts to 80 W.

so i am having this question what should i do if the give data file (.txt) has 4 columns, but different lengths? how can i read them in R? any idea for the following problem? Gas consumption (1000 cubic feet) was measured before and after insulation was put into a house. We are interested in looking at the effect of insulation on gas consumption. The average outside temperature (degrees celcius) was also measured. The data are included in the file "insulation.txt". (a) De...
