DevOps Monitoring System

Overview

This project is a Linux-based monitoring system written in Bash. It provides automated monitoring for network and system health, complete with logging and email alerting.

The system includes:

• Network monitoring (Router, Internet, DNS)
• System monitoring (via monitor.sh and report.sh)
• Logging of all monitoring activity
• Email alerts for failures
• Automatic execution using cron
• Cleanup routines via cleanup.sh

---

Features

• Router connectivity checks
• Internet availability checks
• DNS resolution monitoring
• Persistent system logs in logs/
• Automated email alerts using msmtp
• Cron automation (every 5 minutes)
• Log cleanup scripts to maintain storage

File Structure

devops-monitor/
├── cleanup.sh      # Cleans old logs and temporary files
├── monitor.sh      # Main script to run all monitoring tasks
├── network.sh      # Network-specific monitoring script
├── report.sh       # Optional: generates summary reports
├── logs/           # Stores log files
├── docs/           # Project documentation
└── README.md       # This file

Note: logs/ contains runtime logs and docs/ can store diagrams or documentation.

Installation

Clone the repository:

git clone https://github.com/Xaynerbb/Pulse-Monitor.git
cd devops-monitor

Make all scripts executable:

chmod +x *.sh

---

Usage

Run the monitoring system manually:

./monitor.sh

Log files are stored here:

~/devops-monitor/logs/network-monitor.log

Each run creates a timestamped log entry so you can track network and system status over time.

---

Automation

Set up cron to run the monitor every 5 minutes:

crontab -e

Add the following line:

# Run monitoring every 5 minutes
*/5 * * * * /home/Xaynerbb/Desktop/devops-monitor/monitor.sh

This cron job automates monitoring, logging, and alerting without manual intervention.

Example Log Entry

------------------------------------
Run at: 2026-02-24 08:10:02
2026-02-24 08:10:02 - Router: OK
2026-02-24 08:10:02 - Internet: OK
2026-02-24 08:10:02 - DNS: OK
2026-02-24 08:10:02 - NETWORK STATUS: HEALTHY

Logs are cumulative and provide historical insights for troubleshooting.

Scripts

• network.sh — Checks network connectivity (router, Internet, DNS)
• monitor.sh — Main script to run all monitoring tasks
• report.sh — Generates summary reports (optional)
• cleanup.sh — Removes old logs to keep the system tidy

All scripts are executable and can be run independently or via monitor.sh.
