Operating Structure

Core Components

• dPanel Core: main process, handles API, UI, and configuration.
• Worker Service: background tasks, queue processing.
• Database Layer: PostgreSQL, migrations, and schema management.
• File System: /var/dpanel, logs, backups, and data storage.

Service Interaction Flow

1. User requests via the web UI.
2. API routes to the Core process.
3. Core validates and triggers the Worker if background work is required.
4. Worker performs tasks, updates the database, and writes logs.
5. Core returns the final response to the user.

Monitoring & Logging

• Use Prometheus for metrics collection.
• Visualize with Grafana dashboards.
• Log rotation via logrotate to keep disk usage in check.
