+The **workload group selector** lets you filter and analyze active queries by workload group:
+
+- By default, the selector is set to **All Workload Groups**, showing queries across the cluster.
+- When **WLM is disabled**, only the `DEFAULT_WORKLOAD_GROUP` option is available.
+- When **WLM is enabled**, the dropdown lists all available workload groups.
+- Selecting a specific group filters the dashboard to show only queries running under that workload group.
+- The [metrics](#metrics-overview) panels and charts update to display only the selected workload group.

 ### Canceling live queries
 
 The live queries table provides direct controls for canceling queries that are currently running in the cluster. This allows you to immediately stop problematic or resource-intensive searches without waiting for them to finish. You can cancel live queries in the following ways:
