Which tool should you use to determine if query throttling is occurring in a Fabric warehouse?

• A. the Capacity settings
• B. the Monitoring hub
• C. dynamic management views (DMVs)
• D. the Microsoft Fabric Capacity Metrics app

Answer: (D)

The capacity metrics tool in Microsoft Fabric is what you use to see if query throttling is happening because it focuses on capacity pressure and throttling events across the Fabric environment. It provides a dedicated view of how resources are being consumed, including indicators like saturation, queue lengths, and wait times, so you can quickly confirm whether workloads are being throttled and when that throttling occurs.

Other options serve different purposes: capacity settings let you configure limits but don’t show when throttling is actually happening; the Monitoring hub gives a broad health and telemetry overview without specifically highlighting throttling events; and dynamic management views are low-level diagnostic queries you would run to investigate performance, but they require manual data gathering and interpretation rather than a ready-made, at-a-glance view of throttling.
