Refactored the project from a PostgreSQL connection metrics exporter to a Synapse metrics exporter. This change addresses the need for more specific metrics related to Synapse Matrix servers, instead of the general PostgreSQL connection metrics. Updated the project name, relevant variable names, and configurations to reflect the Synapse focus. Now, the exporter provides metrics such as local users by state, type, and moderation status, total devices, rooms, events, and federation destinations. This update shifts the project's direction to support Synapse server administrators by offering detailed insights into their server's usage and performance.
No existing functionality was removed; instead, the project's aim was realigned to meet the more specialized requirements of Synapse metrics reporting. By focusing on Synapse, the exporter can offer valuable data that was not previously available through the general PostgreSQL connection metrics, potentially contributing to improved server management and user experience on the Synapse platform.
Introduced a new systemd service for the Postgres Connection Exporter, enhancing monitoring capabilities by tracking database connections. This service configuration ensures it starts after the network is available, runs under a dedicated user and group for security, and is set to automatically restart upon failure, ensuring high availability. The setup aims to streamline deployment and maintenance processes for systems requiring constant database connection monitoring.
The service is designed to be easily integrated into multi-user environments, adhering to best practices for system services.
Introduced command-line flags for improved configuration management, including the creation of a default config file, and specified listening address override capabilities. This update facilitates easier and more flexible setup and deployment processes for the PostgreSQL connection exporter. The `.gitignore` and documentation were updated to align with these changes, reflecting the new command-line options and the removal of the `config.dist.yaml` in favor of creating a default configuration through the tool itself.
- Command-line flags `--create-config`, `--config`, `--host`, and `--port` added to streamline customization.
- Configuration now supports naming database hosts for clearer metrics identification.
- Documentation revised to guide through the new configuration and setup process.
- Changelog introduced to track project evolution.
These enhancements aim to make the exporter more adaptable to various deployment environments and to simplify the initial setup for users.
