¿Cómo monitorizo y visualizo la temperatura de la CPU usando Linux?
Como han señalado otros, necesita el paquete lm-sensores . Pensé que debería mencionar que, además de instalar el paquete, debería ejecutar el comando sensores-detect para identificar los módulos del kernel que deben cargarse.
Si no lo ha hecho, ejecútelo manualmente una vez y verifique si detecta algún sensor a bordo de su computadora.
$ 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)
Si tiene suerte, su computadora portátil admitirá una serie de sensores. Si no es así, aún puede encontrar un conjunto básico de sensores para la 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)
