How to read out CPU temperature?

[rowo]

My main board is https://www.gigabyte.com/se/Motherboard/GA-MA69VM-S2-rev-10#ov
I have tried the following as root:

# kldload coretemp
# sysctl dev.cpu.0.temperature
sysctl: unknown oid 'dev.cpu.0.temperature'
# sysctl -a|grep temperature
#


Is there a package similar to Linux "sensors" for FreeBSD? At freshports I only find qt5-sensors but I would prefer a command line tool.

That is a board for AMD CPUs, so you need amdtemp ( coretemp is for Intel processors ), and/or add amdtemp_load="YES" to /boot/loader.conf if you want it automatically loaded at boot time.

And I am not aware of anything like 'lm_sensors' on FreeBSD. However you still can use sysctl.

Thanks!

You might also be interested in sysutils/hwstat. It doesn't paint pretty pictures/graphs on your desktop. But it's nice for monitoring such things, and is easily scriptable.

Thanks!

Some AMD EPYC CPUs don't report their temperature in the dev.cpu.*.temperature sysctls even though amdtemp kernel module is loaded. Any other way to do that, or the mentioned CPUs lack temperature sensors?

sysutils/btop (system information utility, alt. top) also displays the temperature.

sysutils/py311-glances does that too.

Just tried it - no temperature info on a machine that doesn't have temperature sysctls, and shows it on those that do have it.

I found a workaround - query MCE network interface sensors)

dev.mce.3.hw_temperature: 68000
dev.mce.2.hw_temperature: 70000
dev.mce.1.hw_temperature: 57000
dev.mce.0.hw_temperature: 58000

You can ask your mainboard's BMI to report the socket temperature, too, which is what sysutils/ipmitool and sysutils/munin-node does if the ipmi plugin and kernel module is loaded.

In .conkyrc a line

Temperature ${exec sysctl -a|grep temperature | awk '{print $2}' } Celsius
