Introduced `_failure_state` to track consecutive failures per target and `_failure_log_interval_seconds` to control logging frequency. Added logs for recovery when a target recovers and throttled error logs to reduce noise for recurring errors.
Introduced a new optional "from_name" attribute to email settings, allowing customization of the sender's display name in outgoing emails. Updated backend models, APIs, and front-end components to include and handle this field properly. This enhances email clarity and personalization for users.
This commit implements the addition of `target_owners` and `alert_notification_events` tables, enabling management of responsible users for targets. Backend and frontend components are updated to allow viewing, assigning, and notifying target owners about critical alerts via email.
Implemented backend and frontend support for managing SMTP settings for email notifications. Includes API endpoints, database migration, and UI integration for configuring and testing email alerts.
Refactored `_fetchrow_required` and introduced multiple helper functions (e.g., `_run_required_fetch`, `_run_optional`) to streamline query execution and improve readability. Organized the script into distinct sections for better maintainability: connectivity, collector, target endpoints, overview, and optional paths. This enhances clarity and ensures consistency in the smoke testing process.
This update introduces `PG_DSN_CANDIDATES` for specifying multiple DSN options, improving compatibility and CI portability. The script now attempts connections sequentially using the provided candidates before falling back to single DSN or raising an error. Relevant updates to documentation and workflow configuration have also been made.
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.
Introduced a GitHub Actions workflow to verify compatibility with PostgreSQL versions 14 through 18. Implemented a smoke test script to check core database metrics and version-specific differences. Updated the README with details about the compatibility matrix and usage instructions for the script.
Introduced logic to check the existence of `pg_stat_checkpointer` and fetch corresponding statistics when available. This ensures compatibility with newer PostgreSQL versions while maintaining backward support using `pg_stat_bgwriter`.
The migration script's revision ID was adjusted to remove redundancy in the naming. This improves readability and ensures consistency with naming conventions.
This commit introduces a `use_pg_stat_statements` flag for targets, allowing users to enable or disable the use of `pg_stat_statements` for query insights. It includes database schema changes, backend logic, and UI updates to manage this setting in both creation and editing workflows.
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.
This commit introduces a new endpoint to test database connection. The frontend now includes a button to test the connection before creating a target, with real-time feedback on success or failure. Related styles and components were updated for better user experience.
This commit introduces a detailed database overview endpoint and service, providing key metrics such as replication status, database sizes, and performance indicators. On the frontend, a new UI section displays these metrics along with improved forms and troubleshooting tips. Enhancements improve user experience by adding informative tooltips and formatting for byte and time values.
