Score: 5.5/10 (Innovation: 4, Technical: 6, Documentation: 7, Utility: 5)

dbhealth is a Go-based Postgres monitoring agent that runs in a single container, collects health metrics from system catalogs, and exports them to Prometheus, OpenTelemetry, Datadog, or a hosted control plane. It stands out for its careful catalog-based collection, per-table freshness tracking, schema change detection, and a minimal query footprint designed to avoid adding load to the database.

Target audience: backend devs, devops, database admins
