The system monitors freshness, volume, and schema anomalies by collecting metadata snapshots into InfluxDB, comparing current metrics against 6-week baselines using statistical modeling. A key innovation is tracking `last_volume_changed_time` to catch tables that update metadata but contain stale data. The platform includes auto-normalization, importance scoring for critical assets, contextual threshold adjustments (like relaxed monitoring during overnight batch windows), and Slack-based incident management with self-tuning feedback loops that learn team tolerance levels over time. ## Full article daily.dev links to this article rather than hosting it.
