PerfView: ASP.NET Core Stats View
In PerfView v3.1.10, released 02-May-2024, if a trace containing the needed events is opened, there is a new ASP.NET Core Stats view available that shows individual request information along with overall statistics. The events needed to construct this view are available in the .NET Profiler traces that are captured in AppServices (both Windows and Linux) and can be captured manually with other tools like PerfView and dotnet-trace. The view was modeled after the IIS Stats view. It also features clickable ActivityIds for requests so if there's a specific one you want to dig further into, you can click the ActivityId and it will open the Events window and show all events in the trace with that ID within the timeframe of the request.
