View CPU temperature under Linux terminal

In our server routine maintenance, we may care about the server CPU temperature, how to quickly see the CPU temperature in the Linux system? Lm_sensors provides a set of solutions that automatically detects the model and read mode of the motherboard sensor and can be run quickly in command line mode. So we can put the CPU temperature into the daily monitoring.

The following examples are used in the CentOS system installation:

#yum install-y lm_sensors

Then run Sensors-detect to probe the sensor type, this command will give you some questions, answer yes:

[Email protected] ~]# Sensors-detect

# Sensors-detect Revision 1.1

# System:lenovo 4286af2 (laptop)

Determine which kernel modules you need

To the load to use Lm_sensors most effectively. It is generally safe

and recommended to accept the default answers to all questions,

Unless you know ' re doing.

Some South bridges, CPUs or memory controllers contain embedded sensors.

Want to scan for them? This is totally safe. (yes/no): YES

Silicon Integrated Systems SIS5595 ... No

VIA vt82c686 Integrated Sensors ... No

VIA VT8231 Integrated Sensors ... No

AMD K8 Thermal Sensors ... No

AMD Family 11h Thermal sensors ... No

Intel Digital Thermal Sensor ... success!

(Driver ' coretemp ')

Intel AMB Fb-dimm Thermal sensor ... No

VIA C7 Thermal and voltage sensors ... No

Some Super I/O chips contain embedded sensors. We have the to write to

Standard I/O ports to probe them. This is usually safe.

Does want to scan for Super I/O sensors? (yes/no): Y

Some Hardware monitoring chips is 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 the ISA I/O ports even if you don't have any

ISA slots! Does want to scan the ISA I/O ports? (yes/no): Y

Probing for ' Winbond w83781d ' at 0x290 ... No

Probing for ' Winbond w83782d ' at 0x290 ... No

Lastly, we can probe the I2c/smbus adapters for connected hardware

Monitoring devices. The most risky part, and while it works

Reasonably well in most systems, it had been reported to cause trouble

On some systems.

Does want to probe the I2c/smbus adapters now? (yes/no): Y

Found Unknown SMBus adapter 8086:1C22 at 0000:00:1F.3.

Sorry, no supported PCI bus adapters found.

Now follows a summary of the probes I had just done.

Just Press ENTER to continue:

Driver ' coretemp ':

* Chip ' Intel Digital Thermal Sensor ' (CONFIDENCE:9)

Want to Overwrite/etc/sysconfig/lm_sensors? (yes/no): Y

Starting lm_sensors:loading module coretemp [OK]

Unloading I2c-dev ... Ok

Finally run the sensors command to see the CPU temperature:

[email protected] ~]# sensors

acpitz-virtual-0

Adapter:virtual Device

Temp1: +32.0°c (crit = +99.0°c)

thinkpad-isa-0000

Adapter:isa Adapter

coretemp-isa-0000

Adapter:isa Adapter

Physical ID 0: +40.0°c (high = +86.0°c, Crit = +100.0°c)

Core 0: +40.0°c (high = +86.0°c, Crit = +100.0°c)

Core 1: +38.0°c (high = +86.0°c, Crit = +100.0°c)

We can also set the Lm_sensors service to start automatically so that the relevant modules are loaded automatically:

[Email protected] ~]# chkconfig lm_sensors on

[[Email protected] ~]# service lm_sensors start

Starting lm_sensors:loading module coretemp [OK]
