Comparison (deprecated)

Blocked — creation permanently disabled. The comparison YAML key is recognized by the CLI but creation is blocked with: "Creating legacy comparison monitors is no longer supported. Use the v2 metric_comparison monitor instead."

What to use instead

Use metric_comparison for all comparison monitors. It provides a cleaner source/target structure with explicit SQL and warehouse configuration.

montecarlo:
  metric_comparison:
    - name: orders_source_target
      description: Compare order counts between warehouses
      source:
        sql: SELECT COUNT(*) FROM analytics.orders
        warehouse: warehouse_a
      target:
        sql: SELECT COUNT(*) FROM analytics.orders
        warehouse: warehouse_b
      alert_conditions:
        - type: comparison_delta
          metric: ROW_COUNT
          operator: GT
          threshold_value: 10
      schedule:
        type: fixed
        interval_minutes: 720
      domains:
        - my-domain

Migration steps

1. Identify existing comparison monitors in your YAML files.
2. Rewrite each as metric_comparison using the source/target structure above.
3. Apply with montecarlo monitors apply.
