Como outros notaram, você precisa do pacote lm-sensors . Eu pensei que deveria mencionar que, além de instalar o pacote, você deve executar o comando sensors-detect para identificar os módulos do kernel que precisam ser carregados.

Se você não tiver feito isso, execute-o manualmente uma vez e verifique se ele detecta algum sensor em seu computador.

$ sudo sensors-detect 
# sensors-detect revision 5249 (2008-05-11 22:56:25 +0200)

This program will help you determine which kernel modules you need
to load to use lm_sensors most effectively. It is generally safe
and recommended to accept the default answers to all questions,
unless you know what you're doing.

We can start with probing for (PCI) I2C or SMBus adapters.
Do you want to probe now? (YES/no): 
Probing for PCI bus adapters...
Use driver 'i2c-i801' for device 0000:00:1f.3: Intel 82801G ICH7

We will now try to load each adapter module in turn.
Module 'i2c-i801' already loaded.
If you have undetectable or unsupported I2C/SMBus adapters, you can have
them scanned by manually loading the modules before running this script.

We are now going to do the I2C/SMBus adapter probings. Some chips may
be double detected; we choose the one with the highest confidence
value in that case.
If you found that the adapter hung after probing a certain address,
you can specify that address to remain unprobed.

Next adapter: SMBus I801 adapter at 10c0 (i2c-0)
Do you want to scan it? (YES/no/selectively): 
Client found at address 0x50
Probing for 'Analog Devices ADM1033'...                     No
Probing for 'Analog Devices ADM1034'...                     No
Probing for 'SPD EEPROM'...                                 Yes
    (confidence 8, not a hardware monitoring chip)
Probing for 'EDID EEPROM'...                                No
Client found at address 0x52
Probing for 'Analog Devices ADM1033'...                     No
Probing for 'Analog Devices ADM1034'...                     No
Probing for 'SPD EEPROM'...                                 Yes
    (confidence 8, not a hardware monitoring chip)
Probing for 'EDID EEPROM'...                                No

Some chips are also accessible through the ISA I/O ports. We have to
write to arbitrary I/O ports to probe them. This is usually safe though.
Yes, you do have ISA I/O ports even if you do not have any ISA slots!
Do you want to scan the ISA I/O ports? (YES/no): 
Probing for 'National Semiconductor LM78' at 0x290...       No
Probing for 'National Semiconductor LM78-J' at 0x290...     No
Probing for 'National Semiconductor LM79' at 0x290...       No
Probing for 'Winbond W83781D' at 0x290...                   No
Probing for 'Winbond W83782D' at 0x290...                   No
Probing for 'IPMI BMC KCS' at 0xca0...                      No
Probing for 'IPMI BMC SMIC' at 0xca8...                     No

Some Super I/O chips may also contain sensors. We have to write to
standard I/O ports to probe them. This is usually safe.
Do you want to scan for Super I/O sensors? (YES/no): 
Probing for Super-I/O at 0x2e/0x2f
Trying family 'National Semiconductor'...                   No
Trying family 'SMSC'...                                     Yes
Found unknown chip with ID 0x2803
Probing for Super-I/O at 0x4e/0x4f
Trying family 'National Semiconductor'...                   No
Trying family 'SMSC'...                                     No
Trying family 'VIA/Winbond/Fintek'...                       No
Trying family 'ITE'...                                      No

Some south bridges, CPUs or memory controllers may also contain
embedded sensors. Do you want to scan for them? (YES/no): 
Silicon Integrated Systems SIS5595...                       No
VIA VT82C686 Integrated Sensors...                          No
VIA VT8231 Integrated Sensors...                            No
AMD K8 thermal sensors...                                   No
AMD K10 thermal sensors...                                  No
Intel Core family thermal sensor...                         Success!
    (driver 'coretemp')
Intel AMB FB-DIMM thermal sensor...                         No

Now follows a summary of the probes I have just done.
Just press ENTER to continue: 

Driver 'coretemp' (should be inserted):
  Detects correctly:
  * Chip 'Intel Core family thermal sensor' (confidence: 9)

I will now generate the commands needed to load the required modules.
Just press ENTER to continue: 

To load everything that is needed, add this to /etc/modules:

#----cut here----
# Chip drivers
coretemp
#----cut here----

Do you want to add these lines automatically? (yes/NO)

Se você tiver sorte, seu laptop suportará uma variedade de sensores. Caso contrário, você ainda pode encontrar um conjunto básico de sensores para a CPU:

$ sensors
acpitz-virtual-0
Adapter: Virtual device
temp1:       +40.5°C  (crit = +105.0°C)                  

coretemp-isa-0000
Adapter: ISA adapter
Core 0:      +35.0°C  (crit = +100.0°C)                  

coretemp-isa-0001
Adapter: ISA adapter
Core 1:      +40.0°C  (crit = +100.0°C)

Usando 'sensores' (do lm-sensors) e 'watch' (do procps pkg), você pode monitorar em tempo real os dados dos sensores na linha de comando via:

watch -n 1 -d sensors

Isso mostrará os sensores a cada 1 segundo e destacará a diferença do segundo anterior.

Every 1.0s: /usr/bin/sensors

...
temp1:       +55C  (high =   +50C, hyst =   +45C)   sensor = thermistor   ALARM
temp2:     +35.0C  (high =   +80C, hyst =   +75C)   sensor = thermistor
temp3:     +35.0C  (high =   +80C, hyst =   +75C)   sensor = thermistor

Computer Temperature Monitor is a little applet for the GNOME desktop that shows the temperature of your computer CPU and disks on screen.

It also allows you to log temperatures to a file. You can set alarms to notify you when a tempertature is reached. Several monitors can be added to the panel to monitor different sensors. It is designed to look like CPU Frequency Gnome applet, so they match each other on panel.

Para instalar o uso:

sudo apt-get install computertemp

Eu tenho um servidor Dell (Poweredge R420) rodando Fedora / Red Hat Linux . Eu instalei lm_sensors, mas sensors me deu uma mensagem dizendo que os drivers do kernel não foram carregados. Eu usei sensores detectados para descobrir qual sensor eu precisava, e descobri que precisava do IPMI.

Now follows a summary of the probes I have just done.
Just press ENTER to continue:

Driver 'ipmisensors':
  * ISA bus, address 0xca8
    Chip 'IPMI BMC KCS' (confidence: 8)

Warning: the required module ipmisensors is not currently installed
on your system. If it is built into the kernel then it's OK.
Otherwise, check http://www.lm-sensors.org/wiki/Devices for
driver availability.

Eu verifiquei a página, que me aconselhou a usar o ipmitool. Eu instalei, mas ainda assim não funcionaria:

$ ipmitool sensor
Could not open device at /dev/ipmi0 or /dev/ipmi/0 or /dev/ipmidev/0: No such file or directory
Get Device ID command failed
Unable to open SDR for reading

Depois de mais algumas pesquisas, me deparei com esta página: link

O script ipmimod.sh funcionou pronto para mim:

#!/bin/bash

#IPMI kernel module installer for Redhat-style machines
#dranch-3r7Miqu9kMnR7s880joybQ@xxxxxxxxxxxxxxxx

#07/26/06 - use absolute paths for modprobe
#05/01/06 - orig version

/sbin/modprobe ipmi_devintf

maj='cat /proc/devices | awk '/ipmidev/{print $1}''
echo $maj
if [ -c /dev/ipmi0 ]
then
   rm -f /dev/ipmi0
   /bin/mknod /dev/ipmi0 c $maj 0
else
   /bin/mknod /dev/ipmi0 c $maj 0
fi

IPMI_DRIVERS="ipmi_si ipmi_si_drv ipmi_kcs_drv"
for driver in $IPMI_DRIVERS; do
  find /lib/modules/'uname -r'/kernel/drivers/char/ipmi | grep $driver > /dev/null
  RETURN_VALUE=$?
  if [ $RETURN_VALUE -eq 0 ] ; then
    #Here are specific memory locations for Supermicro AOC-type IPMI cards
    /sbin/modprobe $driver type=kcs ports=0xca8 regspacings=4
    break
  fi
done

Depois de executar isso, finalmente posso ver a temperatura da CPU:

$ ipmitool sensor | grep Temp
Inlet Temp       | 24.000     | degrees C  | ok    | na        | -7.000    | 3.000     | 42.000    | 47.000    | na
Temp             | na         | degrees C  | na    | na        | 3.000     | 8.000     | 77.000    | 83.000    | na
Temp             | na         | degrees C  | na    | na        | 3.000     | 8.000     | 77.000    | 83.000    | na

Espero que isso ajude qualquer pessoa com servidores da Dell a ter dificuldade em obter as temperaturas.

O Linux permite que você acesse sensores de informação de temperatura. Funciona com RH6.2x64.

Este driver contém suporte de leitura usando lm-sensors:

tipo

modprobe coretemp

Eu descobri outro software com gui para monitorar as temperaturas. O nome do software é: Psensor: link

Veja o artigo na Internet: link

Para instalar no Ubuntu / Mint, execute este comando no seu terminal:

sudo apt install psensor

Para executar o aplicativo, basta executar isto:

sudo psensor

Obrigado.

ACPI

Vale mencionar o comando acpi ,

acpi -t   # or -V for all

-t | --thermal: show thermal information

De apt-cache show acpi :

Description-en: displays information on ACPI devices Attempts to replicate the functionality of the "old" apm command on ACPI systems, including battery and thermal information.
Does not support ACPI suspending, only displays information about ACPI devices.

Homepage: http://sourceforge.net/projects/acpiclient

No sistema semelhante ao Ubuntu, você pode instalá-lo com

sudo apt-get install acpi

Observação: você pode monitorar a temperatura com watch -n 1 -d acpi -V ou pode começar a analisar sua saída (ou a sensors one) com um script (com ou sem o comando date ) , adicionando cores, registrando a saída em um arquivo ...

while [[ 1 ]] ; do acpi -t | awk '{printf ("%2.2f ",$4)}'; date; sleep 1 ; done

Você pode retornar a linha de comando em um arquivo conky para mostrá-lo em seu protetor de tela. Ainda é menos inchado que um applet de comer espaço.

sudo apt-get install conky

Em seguida, construa o arquivo .conkyrc dos seus sonhos em sua pasta / home / usuário e adicione-o aos seus aplicativos lançados no início.

IMP: Veja tutoriais sobre tópicos de fórum conky ou premade .conkyrc, Ubuntu e ubuntu-fr, Lifehacker e mais para configurações conky agradáveis.
