🖥️ Linux System Monitor & Maintenance Toolkit

A collection of Bash scripts designed to automate server health monitoring, log management, and disk usage alerts. This project was built to practice shell scripting, process management, and Cron automation.

📂 Project Structure

• master_monitor.sh: The main wrapper script. It orchestrates the execution of all other modules in a specific order to ensure data consistency.
• disk_monitor.sh: Monitors disk usage.
  • Alerts if usage exceeds 80%.
  • Logs "DANGER" or "Safe" status with timestamps.
• system_health.sh: Captures key system metrics.
  • Memory: Calculates and logs RAM usage percentage.
  • CPU: logs the 1-minute, 5-minute, and 15-minute load averages.
• log_archive.sh: Automated housekeeping.
  • Scans specific directories for logs older than 7 days.
  • Moves them to a dedicated archive/ folder to keep the system clean.
