 - **System Health Monitoring**: Reports on system health indicators such as total and used memory, CPU cores, CPU usage, total number of users, active users, and bandwidth metrics.
 - **User Activity Tracking**: Monitors user activity, including data limits, used traffic, lifetime used traffic, and online status within the last 2 minutes.
 - **Version and Start Time Information**: Includes core version information and whether the core service has started successfully.
-- **Configurable via Environment Variables**: Allows customization and configuration through environment variables, making it easy to adjust settings such as metrics port, update interval, and more.
+- **Configurable via Environment Variables and Command-line Arguments**: Allows customization and configuration through both environment variables and command-line arguments, making it easy to adjust settings.
 - **Support for Multiple Architectures**: Docker images are available for multiple architectures, including AMD64 and ARM64, ensuring compatibility across various deployment environments.
 - **Optional BasicAuth Protection**: Provides the option to secure the metrics endpoint with BasicAuth, adding an additional layer of security.
 - **Integration with Prometheus**: Designed to integrate seamlessly with Prometheus, facilitating easy setup and configuration for monitoring Marzban VPN services.
