[0924] Fix typo: install these is -> install these if


--

install these if they are somehow not installed, then configure the sensors
sudo apt-get install lm-sensors
sudo sensors-detect


create a new file (script)
sudo nano /usr/sbin/cpu-temp


Scripts for the CPU detection part of the CPU temp plugin

AMD (Ryzen):
sensors | grep -A3 k10temp | awk '$1 == "Tctl:" { print $2 }' | grep -o '[0-9.]\+' | sed 's/\.//'

Intel - single core
Note: inaccurate for multi-core systems, reads only first core - would be fine if the CPU is single core, however
sensors coretemp-isa-0000 | awk '$1 == "Core" && $2 == "0:" { print $3 }' | grep -o '[0-9.]\+' | sed 's/\.//'

Intel - proper
Note: proper format for multi-core systems
sensors coretemp-isa-0000 | awk '$1 == "Package" && $2 == "id" && $3 == "0:" { print $4 }' | grep -o '[0-9.]\+' | sed 's/\.//'


mark the script as executable
chmod +x /usr/sbin/cpu-temp


run the script
/usr/sbin/cpu-temp


run the following commands to set the custom temp script
sudo omv-env set "OMV_CPU_TEMP_COMMAND" "/usr/sbin/cpu-temp"
sudo omv-env set "OMV_CPU_TEMP_DIVISOR" "10"
sudo omv-salt stage run prepare
sudo omv-mkworkbench all
sudo monit restart omv-engined


undoing the custom temp script is the same as setting it except these two lines
sudo omv-env unset "OMV_CPU_TEMP_COMMAND"
sudo omv-env unset "OMV_CPU_TEMP_DIVISOR"
