VectorData
Freshness monitoring
Pick the tables behind critical KPIs. VectorData compares last-modified style metadata to your warning and critical thresholds.
Steps
1. Choose tables
Start with leadership and ops marts — not every staging table.
2. Set thresholds
Define hours-to-stale that match how the business uses the number (for example warn at 6h, critical at 12h).
3. Review history
Use lag history when writing an incident note or standup update.
Verify
- Watched tables show current lag
- A forced stale demo or threshold breach creates one calm alert
