Server Resource Monitor

A lightweight server monitoring solution that tracks CPU and RAM usage through a secure REST API.

Prerequisites

Before setting up the monitoring service, ensure you have:

1. Domain Name

   • A domain or subdomain that you can configure
   • Access to your domain's DNS settings

2. Server Requirements

   • A VPS or server with:
     • Docker installed
     • Docker Compose installed
     • Ports 80 and 443 available
     • At least 1GB RAM recommended

3. DNS Configuration If using a subdomain (e.g., monitor.yourdomain.com):

   Type: A
   Host: monitor
   Value: Your-Server-IP
   TTL: 3600 (or default)
   

   If using a root domain (e.g., yourdomain.com):

   Type: A
   Host: @
   Value: Your-Server-IP
   TTL: 3600 (or default)
   

Quick Setup

1. One-Line Installation

   curl -fsSL https://raw.githubusercontent.com/kaanmertkoc/simple-monitor/main/setup.sh -o setup.sh && chmod +x setup.sh && ./setup.sh

   Or manually:

   # Download setup script
   wget https://raw.githubusercontent.com/kaanmertkoc/simple-monitor/main/setup.sh
   
   # Make it executable
   chmod +x setup.sh
   
   # Run setup with your domain
   ./setup.sh

That's it! Your monitoring service will be available at https://your-domain.com

Troubleshooting

SSL Certificate Issues

• Ensure DNS is properly configured
• Check if ports 80 and 443 are open
• Wait for DNS propagation (can take up to 48 hours)

To manually trigger certificate renewal:

docker compose run --rm certbot certonly --webroot --webroot-path /var/www/certbot -d

Connection Refused

1. Check if containers are running:

   docker compose ps

2. Check logs:

   docker compose logs -f

   For specific services:

   docker compose logs -f monitor
   docker compose logs -f nginx

Invalid Certificate

• Make sure your domain is pointing to the correct IP
• Check if SSL certificate was generated:

  ls -la certbot/conf/live/your-domain.com/

Common Issues

• Ensure DNS is properly configured
• Check if ports 80 and 443 are open
• Verify domain points to correct IP
• Wait for DNS propagation (up to 48 hours)

Security

This setup includes:

• Automatic HTTP to HTTPS redirection
• Modern SSL configuration
