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.
