    Exclamation libsensors readout says 'alarm': Should I worry?

    Hello,

    I just recently installed libsensors4 from the terminal. I then configured and ran it, mainly to get an idea of my CPU temperatures. I recently installed Ubuntu 11.10 on an older machine with a Core 2 Duo (E6600) 2.4 ghz and this CPU was almost constantly running pretty hot under Vista (about 85c).

    So far, the temps look really good and I was relieved. However, what I'm assuming to be the voltage, has the word 'ALARM' on several lines.

    Here is the readout:
    Code:
    fx510x:~$ sensors
    coretemp-isa-0000
    Adapter: ISA adapter
    Core 0:       +56.0C  (high = +84.0C, crit = +100.0C)
    Core 1:       +51.0C  (high = +84.0C, crit = +100.0C)
    
    emc6d103-i2c-3-2e
    Adapter: SMBus I801 adapter at 4000
    in0:          +1.51 V  (min =  +0.00 V, max =  +3.32 V)  ALARM
    in1:          +1.14 V  (min =  +0.00 V, max =  +2.99 V)  ALARM
    in2:          +3.30 V  (min =  +0.00 V, max =  +4.38 V)
    in3:          +5.06 V  (min =  +0.00 V, max =  +6.64 V)  ALARM
    in4:         +11.98 V  (min =  +0.00 V, max = +15.94 V)  ALARM
    fan1:         856 RPM  (min =    0 RPM)
    fan2:           0 RPM  (min =    0 RPM)
    fan3:         878 RPM  (min =    0 RPM)
    fan4:           0 RPM  (min =    0 RPM)
    temp1:        +34.2C  (low  = -127.0C, high = +127.0C)
    temp2:        +29.1C  (low  = -127.0C, high = +127.0C)
    temp3:        +41.2C  (low  = -127.0C, high = +127.0C)
    cpu0_vid:    +0.000 V
    Is this something I need to worry about? It doesn't look at that close to listed max figures, but I'm not sure if they are higher than what they are supposed to be and how serious I should take the 'ALARM' messages.

    Thanks for any and all help.

    temp3:        +66.0C  (high = +80.0C, hyst = +75.0C)  sensor = thermistor
    cpu0_vid:    +1.388 V
    beep_enable: enabled
    It's been like this for as long as I can remember.
    So, yep, don't worry about it.

    Thanks, that makes me feel better at least.

    Re: libsensors readout says 'alarm': Should I worry?

    If it really bothers you - once you've worked out which temp / voltage sensor is which you can customise the libsensors configuration in libsensors.conf so the labels make sense and the useless sensors aren't shown.

    This might help:
    http://manpages.ubuntu.com/manpages/...rs.conf.5.html

    I know I have one "temp" sensor on mine that permanently shows 66C even from a cold start up lol

    I'm sure there's plenty of other guides to it elsewhere as well

    Cool, thanks for the link. I'm definitely going to try that out. What about Conky? Can Conky be configured to show these values too? I'm not at all familiar with Conky, but have played with it before and gave up because I couldn't get it to look pretty enough. I might give it another go on this machine.

    Re: libsensors readout says 'alarm': Should I worry?

    I have much the same display. I think the ALARM means that if the voltage exceeds the maximum, some kind of alarm gets triggered. I also think that you can disable/enable those alarms in your BIOS. So, all this is really telling you is that alarms have been enabled.
    Mint 15 & 16; MS Win7 & Win8.1.
    Will not respond to PM requests for support -- use the forums.

    Re: libsensors readout says 'alarm': Should I worry?

    I've not used Conky myself but I've seen others discussing sensor applets for it - so presume it must be possible.

    On 10.04 I think I'm using indicator-applet which can neatly put temps and fan speeds up in the top bar. Don't think the same is compatible with the Unity desktop though. Have also seen screenshots from people who have hacked their way about to use Gnome Shell on 11.x who had neat little temp indicators showing. Seems like a lot of work for a temp reading though!

    First thing really is to get the sensors output sane before worrying about where / how to display them

    Have fun.

    My sensors' output:
    Code:
    w83627hf-isa-0290
    Adapter: ISA adapter
    in0:          +1.44 V  (min =  +2.99 V, max =  +3.39 V)  ALARM

    in3:          +2.99 V  (min =  +0.13 V, max =  +1.55 V)  ALARM
    in4:          +3.23 V  (min =  +0.34 V, max =  +0.02 V)  ALARM

    in8:          +3.49 V  (min =  +0.13 V, max =  +1.02 V)  ALARM
    fan1:           0 RPM  (min = 8437 RPM, div = 8)  ALARM
    fan2:        2220 RPM  (min = 3515 RPM, div = 8)  ALARM
    fan3:           0 RPM  (min = 10546 RPM, div = 2)  ALARM
    temp1:        +31.0C  (high = +40.0C, hyst = -121.0C)  sensor = thermistor
    temp2:        +48.0C  (high = +80.0C, hyst = +75.0C)  sensor = diode
    temp3:        +67.5C  (high = +80.0C, hyst = +75.0C)  sensor = thermistor
    cpu0_vid:    +1.388 V
    beep_enable: enabled
    I use this line in my conky
    Code:
    ${execi 60 sensors|grep temp2|cut -c 14-21}
    to get the temp2 (cpu) temperature.
    The line executes sensors every 60 seconds, filters the output to show only the line with the string temp2 in it (grep) and then takes the characters between the 14th and the 21rst (+48.0C) and prints them on conky.
    I don't think it's too difficult to adjust it to your needs.

    Yep, I use conky underneath a transparent Unity panel to display
    * CPU temp and usage
    * HDD and GPU Temps
    * mem usage
    * net up/down speeds

    I like to have all these in the panel so you can easily see them when
    windows are maximized.
    The temperatures are passed through scripts to change the color from grey to orange to red, depending on how hot the temps are.
    All the info and scripts was gleaned from the huge conky thread in the cafe.

    Using your sensors output and temp2
    this is a conky config to start you off.
    This is only visible through a Unity panel made completely transparent
    with ccsm.
