Field Quality (deprecated)

Auto-converted August 2025. All field quality monitors were automatically converted to Custom SQL monitors. The old syntax (type: null_count, table, field) is rejected.

What to use instead

Use a Custom SQL Monitor with an explicit SQL query. The auto-conversion already created custom_sql equivalents of your old monitors -- export them to get the new YAML.

montecarlo:
  custom_sql:
    - name: orders_null_check
      description: Null check on orders.customer_id
      sql: |
        SELECT COUNT(*) FROM warehouse.analytics.orders
        WHERE customer_id IS NULL
      alert_conditions:
        - operator: GT
          threshold_value: 0
      schedule:
        type: fixed
        interval_minutes: 720
      domains:
        - my-domain

Migration steps

1. Export auto-converted monitors in the latest format.
2. Replace field_quality definitions with the exported custom_sql definitions. Use the same name to preserve incident history.
3. Apply with montecarlo monitors apply.
