Find CPU temperature from the command line in FC 17?

[tashirosgt]

What's a way to find the CPU temperature from the command line in FC 17? The /proc/acpi directory doesn't have it anymore.

Well, it is the same for fedora.

I have lm_sensors installed and from terminal:

$ sensors
atk0110-acpi-0
Adapter: ACPI interface
Vcore Voltage: +1.14 V (min = +0.85 V, max = +1.60 V)
+3.3 Voltage: +3.39 V (min = +2.97 V, max = +3.63 V)
+5 Voltage: +4.92 V (min = +4.50 V, max = +5.50 V)
+12 Voltage: +12.14 V (min = +10.20 V, max = +13.80 V)
CPU FAN Speed: 1339 RPM (min = 600 RPM, max = 7200 RPM)
CHASSIS FAN Speed: 0 RPM (min = 600 RPM, max = 7200 RPM)
POWER FAN Speed: 0 RPM (min = 1800 RPM, max = 7200 RPM)
CPU Temperature: +31.0°C (high = +60.0°C, crit = +95.0°C)
MB Temperature: +39.0°C (high = +45.0°C, crit = +95.0°C)

coretemp-isa-0000
Adapter: ISA adapter
Core 0: +46.0°C (high = +76.0°C, crit = +100.0°C)
Core 1: +43.0°C (high = +76.0°C, crit = +100.0°C)

this is from my pc.

Short answer: sensors -f | grep -i temp

As Colors mentioned you'll need the lm_sensors package installed. Then you need to run /sbin/sensors-detect just once as root. After that start the lm_sensors service: systemctl start lm_sensors.service
If you run "systemctl enable lm_sensors.service" then you'll always be able to run the sensors -f command.

[tashirosgt]

Yum reports lm_sensors is already installed. There is no sensors-detect command installed although there is a man page for it. Yum doesn't get anything from "yum install sensors-detect".

sensors -f

reports:

nouveau-pci-0100
Adapter: PCI adapter
temp1:       +131.0°F  (high = +212.0°F, crit = +230.0°F)

k10temp-pci-00c3
Adapter: PCI adapter
temp1:        +54.5°F  (high = +158.0°F)
                       (crit = +194.0°F, hyst = +188.6°F)

fam15h_power-pci-00c4
Adapter: PCI adapter
power1:       91.14 W  (crit =  95.04 W)

which is much less elaborate than your report.

Are you sure about that?:

$ rpm -ql lm_sensors | grep sensors-detect
/usr/sbin/sensors-detect
/usr/share/man/man8/sensors-detect.8.gz

/sbin/sensors-detect is a link to /usr/sbin/sensors-detect, and after you run it as root (it's interactive, you can pretty much accept all the defaults) you'll probably get more detailed output.

sensors is more verbose when run as root than as a normal user, it's because root can get access to some acpi values that a user can't get.

There may have been a /usr/sbin/sensors-detect. Before reading the above replies, I re-installed lm-sensors and there is one now, for sure. I ran it, said YES to every scan, and now I have more detail.

Run as root:

sensors -f
nouveau-pci-0100
Adapter: PCI adapter
temp1:       +131.0°F  (high = +212.0°F, crit = +230.0°F)

k10temp-pci-00c3
Adapter: PCI adapter
temp1:        +54.9°F  (high = +158.0°F)
                       (crit = +194.0°F, hyst = +188.6°F)

fam15h_power-pci-00c4
Adapter: PCI adapter
power1:       91.14 W  (crit =  95.04 W)

in0:          +1.44 V  (min =  +0.00 V, max =  +4.08 V)
in1:          +1.50 V  (min =  +0.00 V, max =  +4.08 V)
in2:          +3.31 V  (min =  +0.00 V, max =  +4.08 V)
+5V:          +3.04 V  (min =  +0.00 V, max =  +4.08 V)
in4:          +3.07 V  (min =  +0.00 V, max =  +4.08 V)
in5:          +2.05 V  (min =  +0.00 V, max =  +4.08 V)
in6:          +4.08 V  (min =  +0.00 V, max =  +4.08 V)
5VSB:         +2.99 V  (min =  +0.00 V, max =  +4.08 V)
Vbat:         +3.23 V  
fan1:        1153 RPM  (min =   10 RPM)  ALARM
fan2:           0 RPM  (min =    0 RPM)
fan3:           0 RPM  (min =    0 RPM)
fan5:           0 RPM  (min =    0 RPM)
temp1:       +104.0°F  (low  = +260.6°F, high = +260.6°F)  sensor = thermistor
temp2:        +96.8°F  (low  = +260.6°F, high = +260.6°F)  sensor = thermal diode
temp3:        +75.2°F  (low  = +260.6°F, high = +140.0°F)  sensor = thermal diode
intrusion0:  ALARM

I'm surprised that "CPU" isn't mentioned explicitly.

Am I correct that the "standard" FC 17-64 installation does not have the temperature information in the /proc/acpi directory? My installation has only /proc/acpi/wakeup.

Is the example given by Colors typical - in that the CPU information is associated with acpi?

Some other questions related to sensors:

An Arch Linux article http://chomaloma.blogspot.com/2009/0...eed-linux.html describes a /etc/sensors.d/sensors.conf file and my "default" FC 17 installation has a man page for sensors.conf, but no sensors.conf file. Would a sensors.conf file have any effect if I created it?

Another Arch Linux oriented article drew my attention to the /sys/class/hwmon directory and the fact that you can get some information from the device by apparently harmless commands like:

 cat /sys/class/hwmon/hwmon0/device/name

I wonder if you can get a temperature report by a similar method.

Yes. And that's what gets created when you run sensors-detect. It only makes sense to have a sensors.conf if you know exactly what hardware the machine has, which is why the sensors-detect program has to be run manually and interactively.

Apparently the file is named /etc/sensors3.conf in FC 17. That's the only thing I have that looks like a sensor configuration file.
