What tools can you recommend for profiling ASP.NET Core applications in docker?

Question

ASP.NET

Hello! There was a need to study the performance of individual endpoints in an ASP.NET Core Web API running in a docker container. It is necessary to study which methods consume the most CPU / RAM and which methods are most executed. The docker container is located in Kubernetes on a remote machine.
Now I'm considering the following options:
1) dotTrace. I tried to run through dotTrace.sh inside the container and read the snapshot through Rider. The snapshot turned out to be not very informative (although maybe I just opened it somehow wrong :))
2) dotnet-trace.
3) Visual Studio Performance Profiler - I have not yet figured out how to connect to a remote process in docker in VS Community 2019.

Can you tell me which tool is worth spending more time to study? Which one will give me the stats I need?

The docker container is located in Kubernetes on a remote machine.

This complicates everything. Usually, it is not worth profiling in production - it is better to write load tests and run in a development environment
As an option for dotnet-trace

1. The base image in docker must be SDK 3.0+
   
2. Installing dotnet-trace in docker

   RUN dotnet tool install --global dotnet-trace
   ENV PATH $PATH:/root/.dotnet/tools

   
   
3. After running the application in a container (write to the console in docker):
   

   dotnet-trace collect --process-id $(pidof dotnet) --providers Microsoft-DotNETCore-SampleProfiler

   
   
4. When everything - press Ctrl + C, in the folder with the application there will be a file trace.nettrace
