🌐 Network Metrics Exporter

A Go-based network metrics exporter that collects and exposes real-time network performance data — including packet statistics, connection status, throughput, and error rates — through a local HTTP endpoint.
This tool enables easy integration with monitoring systems like Prometheus and Node Exporter, providing deep insights into network health and performance.

🚀 Features

📊 Real-Time Network Metrics

• Collects key network metrics such as:
  • Packet counts (sent, received, dropped)
  • Active connections
  • Throughput (upload/download rates)
  • Error and retransmission rates

⚙️ Lightweight & Efficient

• Built in Go, leveraging system APIs (netstat, ifstat, and /proc/net/) for low-overhead data collection.
• Optimized for minimal CPU and memory usage.

🌍 HTTP Metrics Endpoint

• Exposes collected metrics through a local HTTP server, compatible with:
  • Prometheus scrapers
  • Node Exporter text format
• Easy integration with existing monitoring setups.

🧩 Prometheus & Node Exporter Compatibility

• Designed to complement Node Exporter, allowing seamless collection of network metrics alongside CPU, memory, and disk stats.

💻 Local Web Interface

• Simple HTTP endpoint for quick visualization of current network statistics.
• Provides a straightforward, developer-friendly way to monitor system network performance.
