Explanation

INFORMATION_SCHEMA.WAREHOUSE_LOAD_HISTORY provides metrics on virtual warehouse activity including queued load, active load, and blocked queries over time. This view is specifically designed to help identify query queuing and performance bottlenecks. WAREHOUSE_METERING_HISTORY tracks credit consumption, QUERY_HISTORY tracks individual query execution, and Resource Monitors control credit usage - none of these directly surface queuing data the way WAREHOUSE_LOAD_HISTORY does.
