Conky and system temperatures

This newbish conky editing guide is posted as much for my own future reference as yours. wink I don't see any other posts about hddtemp etc. on bl.org so this is a quick guide to setting up conky to show system monitoring information.

CPUs, GPUs, voltages and fans

The first step is to find out what information your hardware provides, and to backup your .conkyrc file! For the latter, type this:

cd
cp .conkyrc .conkyrc-backup

For the former, continue on...

  1. Conky provides a $(hwmon) variable that can read some information, but because chips can report whatever information they want, this may not be useful. You can browse around in /sys/class/hwmon to see what's there (that's what conky reads).

    AFAIK, to simplify/consolidate all the sensor information, it's best to set up the sensors program. This was already installed on my BL box, but not configured. To configure, you type

    sudo sensors-detect

    It will ask your permission to probe in various ways for sensor information. Once it finishes, you can type

    sensors

    to get all the readings from sensors it detected. The tricky part here is figuring out what the information given by the sensors in your hardware mean. For example, here's the sensors output for my system:

    it8720-isa-0228
    Adapter: ISA adapter
    in0:          +0.85 V  (min =  +0.00 V, max =  +4.08 V)
    in1:          +1.49 V  (min =  +0.00 V, max =  +4.08 V)
    in2:          +3.34 V  (min =  +0.00 V, max =  +4.08 V)
    +5V:          +3.01 V  (min =  +0.00 V, max =  +4.08 V)
    in4:          +3.07 V  (min =  +0.00 V, max =  +4.08 V)
    in5:          +2.14 V  (min =  +0.00 V, max =  +4.08 V)
    in6:          +2.14 V  (min =  +0.00 V, max =  +4.08 V)
    5VSB:         +2.98 V  (min =  +0.00 V, max =  +4.08 V)
    Vbat:         +3.25 V  
    fan1:        2020 RPM  (min =   10 RPM)
    fan2:           0 RPM  (min =    0 RPM)
    fan3:           0 RPM  (min =    0 RPM)
    temp1:        +43.0°C  (low  = +127.0°C, high = +127.0°C)  sensor = thermistor
    temp2:        +43.0°C  (low  = +127.0°C, high = +127.0°C)  sensor = thermistor
    temp3:        +42.0°C  (low  = +127.0°C, high = +127.0°C)  sensor = Intel PECI
    cpu0_vid:    +0.000 V
    intrusion0:  OK
    
    k10temp-pci-00c3
    Adapter: PCI adapter
    APU temp:     +26.4°C  (high = +70.0°C)
    
    radeon-pci-0100
    Adapter: PCI adapter
    Radeon temp:  +34.0°C  (crit = +120.0°C, hyst = +90.0°C)

    (Note: this is after i renamed the two identifying themselves as APU temp and Radeon temp, following instructions elsewhere. That step is not necessary.)

    You might find out additional information about what these readings mean by searching the reporting chip name (for example, from googling it8720-isa-0228 i discovered that the in0 reading is the Vcore, in1 is the Vdram, etc.). Once you have deciphered both what each reading represents, and if it has to be modified (maybe the number isn't an actual voltage, or the temperature reads 20 degrees low, for example), you can then display that information in conky as you like.

    In this case, if i use the ${hwmon temp} options from conky, what it returns are temp1, temp2 and temp3 from it8720-isa-0228, which i can tell from experimentation are NOT my GPU or CPU temps (when put under load these don't change quickly). The same source i mentioned above suggests that one of those temps is in fact the CPU casing temperature, but without a reference from the manufacturer it's very difficult to know for sure.

    In any case, there are two ways to access this sensor data in conky. You can specify the hdmon conky variable by indexing into the sensor chip and temperature probe, or you can parse the information directly from the output of sensors. These are covered in the respective two steps.

  2. You can do some comparison between the hwmon output and the sensors output to make sure you use the right data in conky. In my case,

    ${hwmon 0 temp 1}

    is the first temperature probe in the first sensor chip (it8720-isa-0228),

    ${hwmon 1 temp 1}

    is the temperature probe in the second sensor chip (k10temp-pci-00c3), so that's what i'd use to report my CPU temperature, and 

    ${hwmon 2 temp 1}

    is the temperature probe in the GPU. In other words, it seems to index starting at 0 into the sensor chip, in the same order as they are listed in sensors and starting at 1 into the temperature probes. YMMV. See this $(hwmon) link for more details.

  3. If instead for whatever reason you want to parse the output of the sensors command to get the information you want, you can adapt the following. To use the values given for my specific system by the k10temp-pci-00c3 and radeon-pci-0100 sensors (which, one might reasonably assume, are respectively the CPU and GPU temperatures) in conky, we need to parse out that data from the sensors output:

    ${execi 2 sensors | grep APU | cut -c 16-19}
    ${execi 2 sensors | grep Radeon | cut -c 16-19}

    This takes the output from sensors (again, the output on my system is listed above for reference) every 2 seconds, searches for a line containing 'APU' (or 'Radeon') and then trims it down to characters 16-19.

Hard drives

  1. You must first enable the daemon of the hddtemp program that will report to conky.

    sudo nano /etc/default/hddtemp

    Find the line that defines the variable RUN_DAEMON and change it from false to true:

    RUN_DAEMON="true"

    Ctrl-X and "y" to save and exit.

  2. Then you can modify your .conkyrc file in your home directory:
    Menu->Preferences->Conky->Edit Conkys->Default conkyrc
    or

    geany ~/.conkyrc

    and add the conky variables for the hard drive temperatures

    ${hddtemp}°C

    The above will list the temperature for the first hard drive. If you have more than one, you need to specify the device for each:

    ${hddtemp /dev/sda}°C
    ${hddtemp /dev/sdb}°C

    If you want to see all the possibilities, run hddtemp from the console with a wildcard:

    sudo hddtemp /dev/sd?

Putting it all together: Conky code
I've made simple modifications to the default BL conky to display the load and frequency of my CPU cores and the temperatures as discussed above. This is the modified portion of the .conkyrc file:

Re: Conky and system temperatures

Awesome work! Is there anyway to have the ability to change the names from WD10EAC..etc... to a custom name?

Thanks. As you can see in the .conkyrc code, those are just the names i assigned, based on the output of the hddtemp call from the command line. You can change any of the plain text in that partial .conkyrc i posted when you add it to yours... That means anything not inside a

${ }

, which is how conky variables are marked. Of course, you may need to modify what's inside the variables to use the right sources from your own hardware sensors. Hopefully this guide will help you figure that part out.

BTW, as soon as you save the .conkyrc file, you will see the conky reload and reflect the changes. I would suggest you make a backup before you start in case you break it. smile

Re: Conky and system temperatures

@ Pouletic: I normally don't use a big conky, instead a ribbon or line conky for the minimalistic approach.  Decided to employ the script for multiple HDs temps and see what I get, worked nicely.  Thanks - zephyr

Re: Conky and system temperatures

Thank you for this! Many of us are interested in keeping an eye on temperatures.

Pouletic wrote:

If you find that those hwmon temp values are in fact what you want to display, you can do so like this:

${hwmon temp 1}

(or temp 2, etc., see this $(hwmon) link for details).
   Otherwise, you'll have to parse the output of the sensors command to get the information you want.

I'm not a conky expert, but before you go to grep or sed you can access other monitors by setting a number before temp. (See here.) My 'sensors' returns this (edited):

coretemp-isa-0000
Adapter: ISA adapter
Core 0:       +23.0°C  (high = +89.0°C, crit = +105.0°C)
Core 2:       +22.0°C  (high = +89.0°C, crit = +105.0°C)

nouveau-pci-0100
Adapter: PCI adapter
temp1:        +39.0°C  (high = +100.0°C, crit = +110.0°C)

f71889fg-isa-0a00
Adapter: ISA adapter
temp1:        +30.0°C  (high = +255.0°C, hyst = +251.0°C)
temp2:        +28.0°C  (high = +255.0°C, hyst = +251.0°C)
temp3:        +27.0°C  (high = +255.0°C, hyst = +253.0°C)

and I use this

core 0:$alignr${hwmon 0 temp 2}°C
core 2:$alignr${hwmon 0 temp 4}°C
nouveau:$alignr${hwmon 1 temp 1}°C
f71889fg 1:$alignr${hwmon 2 temp 1}°C
f71889fg 2:$alignr${hwmon 2 temp 2}°C
f71889fg 3:$alignr${hwmon 2 temp 3}°C

So hwmon 0 corresponds to ISA, hwmon 1 to nouveau and hwmon 2 to f71889fg. What number to put next isn't obvious - Core 0 is hwmon 0 temp2, and Core 2 is hwmon 0 temp 4. I just tried all the combinations I could think of and compared conky's display with the output of 'sensors' till it sort of made sense...

Thanks. I'm not sure why i never noticed you can index the sensor chip that way. Cool. The execi way does get me one extra numeral of precision, but it's probably more processor intensive, so i'll go with the built-in conky variables.

I'll update the guide.
