monte carlo freshness rule failed error "no update received from metadata collector"

TL;DR

Restore the metadata collector before tuning the rule: the freshness rule has received no update from the collector, so check the collector integration health for that source first, because the rule cannot evaluate data it never receives. A freshness rule with no collector updates is blind, not satisfied. Monte Carlo distinguishes no data from fresh data only if you look at the collector status behind the rule.

monte carlo freshness rule failed error "no update received from metadata collector"

Use this when

• The check or run fails with this symptom: a Monte Carlo freshness rule fails with no update received from metadata collector.
• You are working on a Monte Carlo monitor on a table whose metadata comes from a warehouse or lake collector integration and the failure repeats on the same data or configuration.
• You need the failing rows, rule, or stage isolated before changing thresholds or code.

Not for this skill when

• A table that was renamed or moved, where the rule points at an object the collector no longer reports under that identity.
• The error text names a different tool, stage, or root cause. Match the verbatim error first and use that skill.

Steps

1. Open the integration status for the source in Monte Carlo and check the last successful collection time. Verify: the collector last success is older than the rule window, or current
2. Verify the table still exists under the same fully qualified name the rule monitors. Verify: a rename or move is confirmed or ruled out
3. Check the collector credentials and permissions after any warehouse password or role change. Verify: the collector can read the metadata views it needs
4. Restore collection, then let one collection cycle complete. Verify: the rule receives an update and evaluates normally
5. Add an alert on collector health itself so a silent collector pages before the freshness rules do. Verify: the integration has its own monitor

The symptom phrasing a searcher tries next.

The variant naming the failing stage or tool directly.

Compatibility: Monte Carlo monitors and warehouse collector integrations

Why it happens

Freshness rules evaluate metadata the collector delivers on a schedule. When the integration breaks, through expired credentials, a revoked role, or a renamed object, rules fail with no update received, which reads like a data problem but is an observability pipeline problem.

Edge cases / pitfalls

• Do not extend the rule window to absorb collector outages; that delays real freshness alerts by the same amount.
• After a warehouse migration, collectors often keep polling the old account; verify the account the integration points at.
