Vitaguard: My First Real-time Linux System Health Monitor In Bash

While learning Linux system administration, I wanted a lightweight tool that mirrors what I actually check when supporting or troubleshooting a Linux system. CPU usage, memory, disk space, running processes and whether or not anything critical is showing up in the logs.

Not something complicated or over-engineered. Just fast, short and sweet, directly in the terminal.

So I built VitaGuard, a real-time system health monitor written entirely in Bash.

What the script does VitaGuard provides a continuously updating overview of system health: Resource usage

Logs Scans recent system logs for critical issues Filters for errors such as:

All of this runs in an auto refreshing loop, updating every 5 seconds until you exit.

Why I built it I built VitaGuard to practice Linux administration fundamentals, not just scripting syntax.

This is the kind of script I'd want to have available when I SSH into a VPS or troubleshooting a system under load.
