Quickly monitor your Linux server's vital signs straight from the terminal

• Bash scripting
• Core Linux tools: top, free, df, ps, grep, awk, tail

• Real-time updates (refreshes every 5 seconds)
• Color-coded progress bars for CPU, memory, disk
• Uptime and load average
• Top 5 processes by CPU usage (clean table)
• Recent critical errors from syslog (filtered, max 3 lines)
• Awesome ASCII art header

This script was created to practice my Linux administration and Bash scripting skills:

• Creating visual progress bars and color alerts
• Filtering log noise for useful error reporting
• Making something truly practical that anyone can pick up and run with ease

The script runs in an infinite loop that:

• Clears the terminal screen
• Collects system metrics using standard Linux utilities
• Renders color-coded progress bars and warnings
• Displays process, log and service information
• Sleeps for 5 seconds before refreshing

• Bash
• Linux system with standard core utilities
• Tested on Ubuntu 24.04 (expected to work on most Debian-based distributions)

Tip: Run in a dedicated terminal, it refreshes automatically!

1. Clone the repository
2. Make the script executable: chmod +x vitaguard.sh
3. Run the script (may need sudo): ./vitaguard.sh
4. Watch the stats update, press CTRL+C to exit

• Configurable refresh interval
• Optional non-interactive / one-shot mode
• Improved compatibility across Linux distributions
• Optional HTML/JS web dashboard for remote monitoring
