Measures reported by SFWHStatTest
The business capability supported by Snowflake for any customer is designed around virtual warehouses. The performance and availability of each of the warehouse is critical to business, so it is absolutely important for administrators to keep an eye on warehouse related statistics like running statements, queued statements and warehouse compute capacity available. These metrics help them predict the load on warehouse and take any measures to avoid warehouse failure. This test monitors the user account and collects statistics related to warehouse availability status, status of query statements etc. These metrics provide valuable insights to the administrators about the current working condition of warehouse.
