# OpenVPN Monitor & Profiler

A modern, full-stack management solution for OpenVPN servers. It combines real-time traffic monitoring, historical analytics, and comprehensive user profile/PKI management into a unified web interface.

## �️ Project Architecture

The project is modularized into three core components:

| Component | Directory | Description |
| :--- | :--- | :--- |
| **Core Monitoring** | `APP_CORE/` | Flask-based API (v3) for log parsing, real-time stats, and historical TSDB. |
| **Profiler** | `APP_PROFILER/` | FastAPI-based module for managing PKI, Certificates, and Server Configs. |
| **User Interface** | `APP_UI/` | Vue 3 + Vite Single Page Application (SPA) serving as the unified dashboard. |

## ⚠️ Important Notes

1.  **Environment**: Production deployment relies on Nginx to proxy requests to the backend services. See the [Deployment Guide](DOCS/General/Deployment.md).
2.  **Permissions**: The backend requires `sudo` or root privileges to manage OpenVPN processes and write to `/etc/openvpn`.
