v5.0.0

pgwatch v5 introduces a major update to the PostgreSQL monitoring tool, focusing on enhanced stability, new features, and modernization. Key highlights include:

Major Changes

Schema migration support for PostgreSQL sinks, module version bump to v5, and migration of the web UI from react-scripts to Vite for improved performance and build efficiency.

New Features

Added metrics like stat_statements_jit, new Grafana panels (e.g., "Tables with the oldest non-frozen xid" and "Total index size"), support for reverse proxies on different paths, and functions like admin.maintain_unique_sources() for PostgreSQL sinks. Also includes graceful fallback for local log parsing and a new testutil package.

Improvements

Enhanced dashboards (e.g., Index Overview, Health Check), deprecation of old Stats Statements dashboards, refactoring of recommendation metrics, and better handling of configurations and logs. Minimum retention interval set to 1 hour.

Bug Fixes

Resolved issues with panel queries, data races in Prometheus sink, source config updates, logging, and more. Fixed circular dependencies in config upgrades and improved partition creation logic.

Full Changelog: v4.1.0...v5.0.0

v4.1.0

Warning

pgwatch v4.1 introduced a breaking change to --retention parameter. It must be a valid Postgres interval now instead of integer value used before. So if you used, for example, --retention=90 to keep measurements for 90 days, now you must use --retention="90 days" value!
