When investigating query performance issues in a warehouse, which tool provides insight into throttling?

The Microsoft Fabric Capacity Metrics app is designed specifically to provide insights into the performance and resource utilization of data workloads within a warehouse environment. It includes detailed metrics and monitoring capabilities that allow users to assess the efficiency and responsiveness of their processes. When investigating query performance issues, this tool can highlight whether throttling is occurring, which happens when there is limited capacity available for queries due to high demand or resource constraints.

The app offers visual representations and metrics that are crucial for pinpointing the causes of slow performance, including any indications of throttling that may impact query execution. It helps in understanding how resource allocation is being managed and where bottlenecks may arise. By using this tool, users can take informed actions to optimize performance based on real data.

Other options might provide certain information or settings related to performance, but they do not focus as directly on the specific insights regarding throttling that the Microsoft Fabric Capacity Metrics app offers. For example, the Capacity settings may help configure resource allocation, while the Monitoring hub may show general usage statistics, but neither provides the targeted detail on throttling that is crucial for diagnosing query issues. Dynamic management views (DMVs) also offer performance insights but may not present the comprehensive, user-friendly metrics regarding throttling specifically like the dedicated app
