DevOps Monitoring System

A modular and extensible monitoring system written in Go that monitors server resources and container status.

Features

• Server resource monitoring:
  • CPU usage
  • Memory usage
  • Disk usage
• Container monitoring:
  • Container status
  • Container health
• Alert system:
  • Email notifications
• Modular design for easy extension

Configuration

Edit config/config.yaml to configure:

• Monitoring intervals
• Resource thresholds
• Container details
• Email alert settings

Setup

1. Install dependencies:

go mod download

2. Configure the system in config/config.yaml

3. Build the application:

go build

4. Run the monitoring system:

./devops

Extending the System

To add new monitoring capabilities:

1. Create a new monitor implementation in internal/monitor/
2. Implement the Monitor interface
3. Add configuration in config/config.yaml
4. Register the new monitor in main.go

Requirements

• Go 1.21 or higher
• Docker (for container monitoring)
• SMTP server access (for email alerts)
