RESOURCE_MONITORS. Resource monitors can be modified through either the web interface or SQL: Make sure you are using the ACCOUNTADMIN role (or a role that has been granted the MODIFY privilege on the desired resource monitor). which cancels any statements being executed by the warehouses at the time. Note that this property is not commonly used. If the running query load is low, then you could resize the warehouse to provide more compute resources. Note that actions support thresholds greater than 100. -- Only create a warehouse dedicated to account usage if there are several -- clients (performance monitors, BI packages, etc.) For more details, see Account Usage. Limits can be set for a specified interval or date range. materialized views); the monitor only controls the virtual warehouses created in your account. If you notice that your current workload is considerably higher than normal, open the History page to investigate which queries are contributing to the higher load. Warehouse query load measures the average number of queries that were running The purpose of this post is to provide a starting point for cost monitoring in the Snowflake Cloud Data Warehouse using the power of Tableau for visual analytics. For example, your resource monitor limit is set at 1000 credits, if your warehouse consumes 700 credits, and cloud services consume 300 credits within a specified interval or date range, an alert will be triggered. Monitoring queuing conditions When queries spend a significant time queuing, the overall workload submitted to the warehouse takes longer to execute. set a threshold to 90% instead of 100%). resumed until one of the following conditions is met: The next interval, if any, starts, as dictated by the start date for the monitor. Changing any of these properties does not affect the used credits to-date for the monitor. reach 100% of the credit quota: The SUSPEND action waits for currently-executing queries to finish before suspending the warehouse. If you choose to customize the schedule for a resource monitor, the frequency is relative to the specified start date and time, which is different than Hi @Dewey (Nanigans) , . materialized views).

For a multi-cluster warehouse, decrease the MIN_CLUSTER_COUNT parameter value. Snowflake automatically resumes the warehouse when any statement that requires a warehouse is submitted and the warehouse is the current warehouse for the session. Enables viewing current and past queries executed on a warehouse as well as usage statistics on that warehouse. For example, if you set the start date to January 31, Snowflake subsequently resets the used credits for the resource monitor waiting for other queries to finish running and free compute resources).
