Monitor CPU Usage on Linux Without Lifting a Finger | Automation For Beginners
In this beginner-friendly Linux tutorial, we automate tracking high CPU usage using cron jobs.
You’ll learn how to:
Identify high CPU-consuming processes using the ps command
Save the command into a reusable script
Schedule it with cron to run automatically every 2 minutes
Track CPU usage over time without manual work
This video is part of the "Automate That Boring Stuff" series, where we automate common Linux tasks using simple tools.
Perfect for beginners learning Linux, cron jobs, system monitoring, and basic automation.
