Replaced all inline error messages with the standardized `api_error` helper for consistent error response formatting. This improves clarity, maintainability, and ensures uniform error structures across the application. Updated logging for collector failures to include error class and switched to warning level for target unreachable scenarios.
Replaced hardcoded standard alert metadata with API-driven data. This change ensures the standard alert information is dynamically loaded from the backend, improving maintainability and scalability. Also adjusted the frontend to handle cases where no data is available.
Introduced new parameters to fine-tune rollback ratio alerts and reduce false positives on low-traffic databases. Adjusted evaluation logic to account for minimum rollback counts and transaction volumes, ensuring more reliable alert thresholds. Updated .env.example and descriptions for better configuration clarity.
Introduced `ALERT_ACTIVE_CONNECTION_RATIO_MIN_TOTAL_CONNECTIONS` to reduce false positives by requiring a minimum number of total connections before evaluating the active connection ratio. Updated the logic and description in relevant files for clarity and configurability.
Introduced a new helper function `_rollback_ratio_recent` to calculate the rollback ratio over the last 15 minutes, ensuring meaningful evaluation only when a minimum transaction threshold is met. Adjusted warning and alert thresholds for rollback ratio and added a contextual metric for transaction volume in the past 15 minutes.
This commit introduces alert management capabilities, including creating, updating, listing, and removing custom SQL-based alerts in the backend. It adds the necessary database migrations, API endpoints, and frontend pages to manage alerts, enabling users to define thresholds and monitor system health effectively.
