- Added functionality to save full metrics periodically and on application shutdown, improving data persistence.
- Introduced new database tables for performance metrics, status code history, popular paths, and referer history, enhancing data tracking capabilities.
- Updated the GetRecentMetrics function to utilize window functions for more accurate metrics retrieval and ensure non-negative values.
- Improved data handling by ensuring empty records are returned instead of null when no metrics are available.
These changes significantly enhance the metrics collection and storage process, providing a more robust framework for performance monitoring.
- Introduced safe type conversion functions for memory usage, status code stats, top paths, and recent requests to prevent panics when accessing metrics data.
- Updated MetricsHandler to utilize these safe functions, improving the robustness of metrics handling.
- Refactored GetStats method in Collector to ensure all fields are initialized and to streamline the retrieval of metrics data.
- Enhanced the overall structure of metrics data for better clarity and reliability in reporting.
- Added new dependency on github.com/mattn/go-sqlite3 for improved metrics storage.
- Updated main.go to initialize metrics collector with a new database path and configuration settings.
- Enhanced config.json to include additional metrics settings such as alert configurations and latency thresholds.
- Refactored internal metrics handling to support new metrics structures and improve data retrieval.
- Introduced a new metrics history endpoint for retrieving historical data, enhancing monitoring capabilities.
- Improved UI for metrics dashboard to include historical data visualization options.
- Added support for tracking top referers in the metrics collector, allowing for better insights into request sources.
- Updated MetricsHandler to include top referers in the metrics response.
- Enhanced the metrics UI to display a new section for the top 10 referers, improving visibility into traffic sources.
- Refactored request recording to capture referer information in the collector for comprehensive statistics.
- Enhanced metrics collection in ProxyHandler, MirrorProxyHandler, and FixedPathProxyMiddleware.
- Introduced a centralized metrics collector to streamline request tracking and statistics reporting.
- Updated MetricsHandler to utilize new metrics structure, including total bytes, requests per second, and error rates.
- Improved documentation in readme.md to reflect new features and usage instructions.
- Added support for metrics monitoring at `/metrics/ui` for better visibility into proxy performance.
