Below is a screenshot of Microsoft’s Real Time Denoised Ambient Occlusion sample, containing Nsight Perf SDK instrumentation. Each render pass or phase of execution has been annotated to take a measurement.

From the DispatchRay call’s HTML report, the following tables show the shader’s pipeline utilization and latency reasons. Quickly spot the most utilized pipelines via the bar charts, and inspect the exact numbers of operations performed.

This sample is bundled with the Nsight Perf SDK, which you can download from the product page.
