While going through some useless ways of not finding software that shows me any good overall "summary" of a good source of temperatures from devices on Linux... I did something quick and dirty... unsure if this is useful, but for me its quite...
#!/bin/bash
# Author: forykw
# Date: 2024/03/13
# Get all devices
DEVICES=`lsscsi | rev | tr -s " " | awk '{print $1}' | rev`
# Loop the temperature lines
for i in `echo ${DEVICES}`
do
# Read the 'for' loop 'per line' instead of per 'space'
IFS=$'\n'
# First grep is what you want to target from temperature outputs and the second grep is what you want to ignore from some settings (example configs and settings about warnings)
for j in `smartctl -a $i | grep -i temperature | grep -vi -e critical -e warning`
do
# Customizable output in case you need to drop more context in a per device output "found" line
echo "[$i]: "$j
done
done
Copy the above into (for example) a file named hdd_temps.sh and then chmod +x hdd_temps.sh and then run it.
Recall this needs the following commands to be available, so test first if you have them installed:
- lsscsi
- smartctl
Depending on the system you can find online how to get these. But in Ubuntu it's a simple:
apt install -y lsscsi smartmontools
I needed this for some local "safeguards"... hence why...
Leave you with an example of how the output looks like:
