network-monitor

A simple Rust application that captures and monitors network packets on a specified network interface, periodically
printing and saving packet metrics to a JSON file.

• Counts the total packets and bytes captured.
• Outputs metrics to the console every 5 seconds.
• Saves metrics snapshots to a JSON file (metrics.json).

Prerequisites

• Rust: Ensure that Rust is installed. Install Rust
• pnet crate: This application uses the pnet crate for network interface handling and packet processing.

Installation

1. Clone the repository:

   git clone https://github.com/JeromeWolff/network-monitor.git
   cd network-monitor

2. Build the project:
