Linux Temperature and Load Monitoring

In short, this is a helper script that I created to log relevant information for troubleshooting my overheating machine, which was causing CPU throttling and a less-than-desirable computing experience.

This script does the following:

  • Retrieve and log CPU core temperatures
  • Retrieve and log computer fan speed
  • Retrieve and log system load for the past minute
  • Retrieve and log any systemd journal entries indicating a throttled CPU condition
  • Notify (GNOME desktop environment) if a throttled CPU condition has been met

This script makes a handful of assumptions (primarily because this was made for my environment):

  • Using systemd (for throttle log entries)
  • Using GNOME (for desktop notifications)
  • The lm_sensors package must be installed (on Fedora: $ sudo dnf install -y lm_sensors)

Scheduling the script

I have scheduled this script to run every minute. This is the crontab entry to accomplish this (crontab -e):

* * * * * /home/trstringer/dev/python/temp-monitor/app.py
