Setting up lm sensors: Difference between revisions

Latest revision as of 09:24, 16 January 2025

This page documents how to set up lm-sensors in Alpine Linux. lm-sensors is a Linux hwmon subsystem that provides tools and drivers for monitoring temperatures, voltage, and fans.

Installation

Install the neccessary packages.

# apk add lm-sensors lm-sensors-sensord lm-sensors-detect

Note: If you already know the name of the sensor module, you can modprobe it now, and skip the lm-sensors-detect install.

Configuration

Load the i2c-dev module:

# echo i2c-dev >> /etc/modules-load.d/i2c.conf # modprobe i2c-dev

Run sensors detect:

# sensors-detect

There are multiple types of sensors that you must skip scanning for (answer no to the prompt) because grsec will not allow you to access /proc/port. If you encounter an error that says something like /dev/port: no such file.., re-run the script and answer no to that question on the next attempt. Examples of ones that you must enter no for: ISA bus, other Super I/O sensors, and IPMI.

Be sure to enter yes (non-default) for the question Do you want to generate /etc/conf.d/lm_sensors?

You will not need perl anymore. Remove it before you forget.

# apk del lm-sensors-detect

Make services start during next reboot.

# rc-update add lm_sensors default # rc-update add sensord default

Start services:

# rc-service lm_sensors start # rc-service sensord start

If you're using Diskless Mode, don't forget to save your new server configuration using

# lbu commit
