• Reading cpu temperature Intel Celeron (R) with lm-sensors

  - by tim_a

  I know there are already a lot of questions like this, but non of the answers provided there could fix my problem. I try to read out my cpu temperature with lm-sensors on my ubuntu 10.04 LTS installation but I can't get to work. I did try the command sensors-detect several times but still nothing. My computer is an old PC with an Intel Celeron (R) @ 2.60 GHz. The odd thing is that the hdd temp is shown in the applet but when I type in the terminal sensors I get the error: "No sensors found! Make sure you loaded all the kernel drivers you need." I'm not really interested in the hdd temperature but I think it is strange that these sensors do work in the applet and not in the terminal. This is the output that sensors-detect gives: http://pastebin.com/F4hVKaLU Any suggestions?

• lm-sensors - always returns 32 degrees (celsius) for temperature

  - by mopoke

  On my VIA EPIA motherboard (using VIA VT8231 ISA bridge), I get strange output for the lm-sensors temperature reading. It always returns 32 degrees (celsius). I have previously had correct output for temperature (my munin graphs show temperatures typically in the range of 50 to 60 degrees. I've tried uninstalling (and purging) the lm-sensors package, have re-run sensors-detect a number of times and rebooted but nothing seems to change the output. I am running Ubuntu Karmic Koala (9.10). Anyone got any bright ideas on what I might have missed? uname -a: Linux george 2.6.31-16-386 #53-Ubuntu SMP Tue Dec 8 06:39:34 UTC 2009 i686 GNU/Linux cpuinfo: processor : 0 vendor_id : CentaurHauls cpu family : 6 model : 7 model name : VIA Samuel 2 stepping : 3 cpu MHz : 399.000 cache size : 64 KB fdiv_bug : no hlt_bug : no f00f_bug : no coma_bug : no fpu : yes fpu_exception : yes cpuid level : 1 wp : yes flags : fpu de tsc msr cx8 mtrr pge mmx 3dnow up bogomips : 800.04 clflush size : 32 power management: lspci: 00:00.0 Host bridge: VIA Technologies, Inc.

• LM Sensors always returning same (invalid) value for one temp sensor

  - by pkaeding

  I am trying to monitor the temp sensors on a server, and plot them using Cacti. I have lm-sensors installed and working correctly. For example, here is the output from sensors: % sensors acpitz-virtual-0 Adapter: Virtual device temp1: +26.8 C (crit = +100.0 C) temp2: +32.0 C (crit = +60.0 C) coretemp-isa-0000 Adapter: ISA adapter Core 0: +36.0 C (high = +105.0 C, crit = +105.0 C) coretemp-isa-0001 Adapter: ISA adapter Core 1: +42.0 C (high = +105.0 C, crit = +105.0 C) However, when I try to get this data via SNMP, I get only one sensor's temperature correctly, and another one always returns 100.000 C: % snmpwalk -Os -c public -v 1 10.8.0.18 -m ALL lmTempSensors lmTempSensorsIndex.1 = INTEGER: 0 lmTempSensorsIndex.2 = INTEGER: 1 lmTempSensorsDevice.1 = STRING: temp1 lmTempSensorsDevice.2 = STRING: temp1 lmTempSensorsValue.1 = Gauge32: 26800 lmTempSensorsValue.2 = Gauge32: 100000 So, my question is two-fold: Why is the second sensor that is returned by SNMP giving a value of 100 C (when it should be 32 C) Why are my CPU core sensors not being returned by SNMP?

• re-point LM to a new vCenter (share same database)

  - by CapiZikus

  1) I'm planning to create a new vCenter server which database point to the same db as current vCenter (the one LM pointing to atm), Then I'm planning to repoint the LM to a new vCenter, ( the new one will see the same esx host, datastore, etc) Is LM will be okay if I do this? 2) The currect VC is a dediated server and a new vCenter will be VM, the current vCenter has database installed on local machine (inc update manager as well) I'm planning to move the local db to cluster db then point the current vCenter to this new cluster and make sure everything is working before promote a new one. Update manager will also has it own VM and point to a new db cluster. Is anythingelse I miss out or need to pay more attention on? thanks

• Best practices for setting lm-factor in Squid refresh patterns

  - by Mpentecost

  I am running a Squid (3.1) cache in front of Django. The content of the site does not change very often, so Squid gives our backend much needed breathing room. Currently, this is the refresh pattern that we are using to cache the content: refresh_pattern . 60 100% 60 We basically want to cache everything for at least an hour (and only an hour) before Squid then re-validates the content. My question is on the "100%" parameter, which sets the lm-factor. I'm not sure if setting that to 100% is doing what we want it to. The assumption was that by setting it to 100%, it would ensure that objects stay in the cache for the max cache time. Is this an incorrect assumption? What are the best practices that one should follow when setting up a refresh pattern like this?

• Temperature monitoring on Dell Precision M4500 under Linux: sensors-detect doesn't, what next?

  - by Tikitu

  I have a Dell Precision M4500, Intel Core i5 CPU, running Linux (Ubuntu Lucid), and would like to keep an eye on CPU temperature. I've tried lm-sensors: sensors-detect didn't find any sensors; following its hint ("This is relatively common on laptops, where thermal management is handled by ACPI rather than the OS.") I tried acpi -V but got nothing thermal. The Gnome panel applet "Hardware Sensors Monitor" reports on GPU temperature but nothing else. What should I be trying next?

• What does the fan speed sensor really report?

  - by T. Verron

  I have an overheating issue on my netbook (ASUS EeePC 1015PW), which I'm trying to troubleshoot. Using lm-sensors while overheating gave me this output : acpitz-virtual-0 Adapter: Virtual device temp1: +86.0°C (crit = +100.0°C) eeepc-isa-0000 Adapter: ISA adapter fan1: 4089 RPM coretemp-isa-0000 Adapter: ISA adapter Core 0: +82.0°C (crit = +100.0°C) Core 1: +80.0°C (crit = +100.0°C) But I can't hear the fan. So I enabled manual pwm controling and set the fan to full speed, and after a few minutes I got this output : acpitz-virtual-0 Adapter: Virtual device temp1: +65.0°C (crit = +100.0°C) eeepc-isa-0000 Adapter: ISA adapter fan1: 4016 RPM coretemp-isa-0000 Adapter: ISA adapter Core 0: +62.0°C (crit = +100.0°C) Core 1: +58.0°C (crit = +100.0°C) And this time I could hear the fan spinning. So there's quite obviously an issue with either fan control or fan monitoring. Hence the question : what kind of physical information does the fan sensor really report? Thank you PS. I should have added that the computer is a small, hard-to-disassemble netbook, so I can't and don't want to try experiments like "block the fan and see what the sensor reports".

• How to remove "Standard Error" column from xtable() output of an lm on R/RSweave/LaTeX

  - by Lucas Spangher

  I'm currently doing some data analysis on population data, so reporting the standard errors in the tables of parameter coefficients just doesn't really make statistical sense. I've done a fair bit of searching and can't find any way to customize the xtable output to remove it. Can anyone point me in the right direction? Thanks a lot, I didn't post this lightly; if it's something obvious, I apologize for having wasted time!

• System Expandable-String Environment Variables Can’t Reference User Environment Variables

  - by Synetech inc.

  Hi, I’ve run into a bit of a situation with Windows environment variables. I’ve narrowed it down to what may or may not makes sense and/or possibly be by design. It seems that expandable-string environment variables of the local machine cannot reference environment variables of the current user. For example if you’ve got the following environment variables: [HKCU\Environment] "CU"="CU" "CU->LM"="%LM%" [HKLM\SYSTEM\CurrentControlSet\Control\Session Manager\Environment] "LM"="LM" "LM->CU"="%CU%" Then you get the following results: > set CU CU=CU CU->LM=LM > set LM LM=LM LM->CU=%CU% It seems that user variables can expand system variable references, but system variables cannot expand (access?) user variable references. I suppose that it makes sense if you think about it just right (eg like how user vars override/hide system vars of the same name), but it also doesn’t make sense if you think about it in even more ways. So what’s going on? Is there a way to get this to work as expected? Thanks.

  I’m trying to get the CPU temperature for my AMD-FX8350 on Debian Squeeze. I ran sensors-detect and then sensors, but I only get my motherboard sensors (it8720-isa-0228). There are three temperature values there but I assume those are not for the CPU. it8720-isa-0228 Adapter: ISA adapter in0: +1.36 V (min = +0.00 V, max = +4.08 V) in1: +1.50 V (min = +0.00 V, max = +4.08 V) in2: +3.38 V (min = +0.00 V, max = +4.08 V) in3: +2.93 V (min = +0.00 V, max = +4.08 V) in4: +3.07 V (min = +0.00 V, max = +4.08 V) in5: +4.08 V (min = +0.00 V, max = +4.08 V) in6: +4.08 V (min = +0.00 V, max = +4.08 V) in7: +2.93 V (min = +0.00 V, max = +4.08 V) Vbat: +3.01 V fan1: 3375 RPM (min = 10 RPM) fan2: 0 RPM (min = 0 RPM) fan3: 1730 RPM (min = 10 RPM) fan5: 0 RPM (min = 0 RPM) temp1: +27.0°C (low = +127.0°C, high = +127.0°C) sensor = thermistor temp2: +53.0°C (low = +127.0°C, high = +127.0°C) sensor = thermal diode temp3: +65.0°C (low = +127.0°C, high = +90.0°C) sensor = thermal diode cpu0_vid: +0.000 V Is there anything I am missing? I also loaded the K8temp and K10temp modules and ran sensor-detect without any results. I do see this message in dmesg: hwmon-vid: Unknown VRM version of your x86 CPU

• Thinkpad Edge e320 thermal sensors description

  - by koressak

  I have a quite specific question concerning description of thermal sensors of my notebbok Thinkpad Edge E320. I have a debian linux installed with lm_sensors package and running command sensors show eight different values without any description of course (temp1 through temp6). I would like to know which one is which (cpu, gpu, hdd, etc.) Using google I didn't find any specific material concerning this exact model. Coult someone point me in the right direction? Thank you in advance.

• Can I get sensible labels for lm-sensors output for "applesmc-isa-0300"?

  - by TK Kocheran

  2011 8,3 Macbook Pro running 64bit 11.10. When I run sensors from the lm-sensors package, I get a lot of information, but no way to understand it: coretemp-isa-0000 Adapter: ISA adapter Physical id 0: +53.0°C (high = +86.0°C, crit = +100.0°C) Core 0: +53.0°C (high = +86.0°C, crit = +100.0°C) Core 1: +52.0°C (high = +86.0°C, crit = +100.0°C) Core 2: +50.0°C (high = +86.0°C, crit = +100.0°C) Core 3: +49.0°C (high = +86.0°C, crit = +100.0°C) applesmc-isa-0300 Adapter: ISA adapter Left side : 2001 RPM (min = 2000 RPM) Right side : 2001 RPM (min = 2000 RPM) TB0T: +33.2°C TB1T: +33.2°C TB2T: +29.0°C TC0C: +52.8°C TC0D: +47.2°C TC0E: +51.8°C TC0F: +53.0°C TC0J: +1.0°C TC0P: +44.5°C TC1C: +52.0°C TC2C: +52.0°C TC3C: +52.0°C TC4C: +52.0°C TCFC: +0.2°C TCGC: +51.0°C TCSA: +52.0°C TCTD: +0.0°C TG0D: +44.5°C TG0P: +43.2°C THSP: +37.5°C TM0S: +57.5°C TMBS: +0.0°C TP0P: +50.0°C TPCD: +55.0°C The core temp info is really useful and I'm pretty sure that Left/Right Side refers to the two fans within, but otherwise, I have no idea what this information means. Is there something I can use to normalize this information?

• Library order is important

  - by Darryl Gove

  I've written quite extensively about link ordering issues, but I've not discussed the interaction between archive libraries and shared libraries. So let's take a simple program that calls a maths library function: #include <math.h int main() { for (int i=0; i<10000000; i++) { sin(i); } } We compile and run it to get the following performance: bash-3.2$ cc -g -O fp.c -lm bash-3.2$ timex ./a.out real 6.06 user 6.04 sys 0.01 Now most people will have heard of the optimised maths library which is added by the flag -xlibmopt. This contains optimised versions of key mathematical functions, in this instance, using the library doubles performance: bash-3.2$ cc -g -O -xlibmopt fp.c -lm bash-3.2$ timex ./a.out real 2.70 user 2.69 sys 0.00 The optimised maths library is provided as an archive library (libmopt.a), and the driver adds it to the link line just before the maths library - this causes the linker to pick the definitions provided by the static library in preference to those provided by libm. We can see the processing by asking the compiler to print out the link line: bash-3.2$ cc -### -g -O -xlibmopt fp.c -lm /usr/ccs/bin/ld ... fp.o -lmopt -lm -o a.out... The flag to the linker is -lmopt, and this is placed before the -lm flag. So what happens when the -lm flag is in the wrong place on the command line: bash-3.2$ cc -g -O -xlibmopt -lm fp.c bash-3.2$ timex ./a.out real 6.02 user 6.01 sys 0.01 If the -lm flag is before the source file (or object file for that matter), we get the slower performance from the system maths library. Why's that? If we look at the link line we can see the following ordering: /usr/ccs/bin/ld ... -lmopt -lm fp.o -o a.out So the optimised maths library is still placed before the system maths library, but the object file is placed afterwards. This would be ok if the optimised maths library were a shared library, but it is not - instead it's an archive library, and archive library processing is different - as described in the linker and library guide: "The link-editor searches an archive only to resolve undefined or tentative external references that have previously been encountered." An archive library can only be used resolve symbols that are outstanding at that point in the link processing. When fp.o is placed before the libmopt.a archive library, then the linker has an unresolved symbol defined in fp.o, and it will search the archive library to resolve that symbol. If the archive library is placed before fp.o then there are no unresolved symbols at that point, and so the linker doesn't need to use the archive library. This is why libmopt needs to be placed after the object files on the link line. On the other hand if the linker has observed any shared libraries, then at any point these are checked for any unresolved symbols. The consequence of this is that once the linker "sees" libm it will resolve any symbols it can to that library, and it will not check the archive library to resolve them. This is why libmopt needs to be placed before libm on the link line. This leads to the following order for placing files on the link line: Object files Archive libraries Shared libraries If you use this order, then things will consistently get resolved to the archive libraries rather than to the shared libaries.

• Strange behavior of I() in left-/right-hand side of formula

  - by adibender

  set.seed(98234) y <- rnorm(100) x <- rnorm(100) lm0 <- lm(y ~ x) lm1 <- lm(I(y) ~ I(x)) all work perfectly fine and I guess we can agree that ´lm0´ is what one would expect to happen. lm1 is equal to lm0 (judging by coefficients). So are set.seed(98234) lm3 <- lm(I(rnorm(100)) ~ rnorm(100)) set.seed(98234) lm4 <- lm(rnorm(100) ~ I(rnorm(100))) But when I() is on neither or both sides of the formula I don't get the results from above: set.seed(98234) lm2 <- lm(I(rnorm(100)) ~ I(rnorm(100))) set.seed(98234) lm5 <- lm(rnorm(100) ~ rnorm(100)) Any ideas why?

• Difference between HashMap, LinkedHashMap and SortMap in java

  - by theband

  Map m1 = new HashMap(); m1.put("map", "HashMap"); m1.put("schildt", "java2"); m1.put("mathew", "Hyden"); m1.put("schildt", "java2s"); print(m1.keySet()); print(m1.values()); SortedMap sm = new TreeMap(); sm.put("map", "TreeMap"); sm.put("schildt", "java2"); sm.put("mathew", "Hyden"); sm.put("schildt", "java2s"); print(sm.keySet()); print(sm.values()); LinkedHashMap lm = new LinkedHashMap(); lm .put("map", "LinkedHashMap"); lm .put("schildt", "java2"); lm .put("mathew", "Hyden"); lm .put("schildt", "java2s"); print(lm .keySet()); print(lm .values()); What is the difference between these three? I don't see any difference in the output as all the three has keySet and values. What are Hashtables?
