sys.dm_workload_management_workload_groups_stats (Transact-SQL)

Applies to: yesAzure Synapse Analytics

Returns workload group statistics and the effective values of the workload group in Azure Synapse Analytics (SQL Data Warehouse).

Column Name Data Type Description Range
group_id int Unique ID of the workload group.
name sysname Name of the workload group.
statistics_start_time datetime Time that statistics collection began for the workload group. The value is either when the workload group was created or when instance is paused or scaled.
total_request_count bigint Cumulative count of completed requests in the workload group.
total_shared_resource_reqeusts bigint Cumulative count of completed requests in the workload group that used resources from the shared pool.
total_queued_request_count bigint Cumulative count of requests queued after the max_concurrency limit was reached.
total_request_execution_timeouts bigint Cumulative count of requests in the workload group that timed out before completion based on the query_execution_timeout_sec setting.
effective_min_percentage_resource tinyint The effective min_percentage_resource setting allowed considering the service level and the workload group settings. The effective min_percentage_resource can be adjusted higher on lower service levels. For example, on DW100c, the lowest min_percentage_resource allowable is 25%. The min_percentage_resource is adjusted to 0% if the value cannot be granted at the service level. For example, min_percentage_resource set to 10% at DW6000c, would have an effective_min_percentage_resource of 0% when scaled down to DW100c.
effective_cap_percentage_resource tinyint The effective cap_percentage_resource for the workload group. If there are other workload groups with min_percentage_resource > 0, the effective_cap_percentage_resource is lowered proportionally.
effective_request_min_resource_grant_percent decimal(5,2) The effective runtime value for request_min_resource_grant_percent of the workload group. The effective value considering the service level and how the workload group is configured. If min_percentage_resource is adjusted because of the service level, effective_request_min_resource_grant_percent will be adjusted accordingly.
effective_request_max_resource_grant_percent decimal(5,2) The effective runtime value for request_max_resource_grant_percent of the workload group considering the configuration of the all workload groups.
