Hi, I need exact values of performance of my program from performance profiler, for documentation of my program, the problem, I need values that have been collected from my program in order to data organize and document it, I have already extracted the diagsession file, etl file in this documentation is useless, I need the summery that is being calculated on swimlanes, I have already figured out that it uses data in the counters file inside the diagsession file to show the summery, the v inside the counters file stands for value, t is stands for time which includes the components of l and h, l is in nano seconds, but I have no idea what negative in l variable means, and what h means, therefore how time is being calculated with the help of l and h variables. so I would be glad if you help me in this so I can finish my program documentation

Hello @Rambod Mokhtari,
Welcome to Microsoft Q&A forum.
I wonder if your diagnostics counter is an ETL file?
Is the file about the dumping file mentioned in this link?
Feel free to contact us.
@Zhengye Xu-MSFT no, there is a file with format of .counters, unfortunately it's not documented I don't know why?
but I can share a couple of screenshots of it and say what I have figured out about this file
this is the file inside the diagsession and when I extract it and open it in notepad++ this is what I see
at first it seems like a pile of numbers, until you notice visual studios summery view of diagnostics session is actually saved in this file, I have figured most of it out but I still have problem with timing of this file
you see here that I underlined some parameters, this is for example of course, you see gpu busy, it means that part is defining gpu usage summery, P is for Points which defines the points that should be graphed for summery of gpu usage, t is for time, I'm not quite sure what l and h is there for, and there is v for value, actually the points are in order, values are literal values of points of vertical axis, and t is for defining the position of points on horizontal axis, and l is in nano seconds so actually if h is 0 and l is not negative, the position of point on horizontal axis is just l divided by a billion, but when h is not 0, the position of point of horizontal axis is more than 2 seconds actually my estimation is that every iteration of h is about 4.28 seconds, why this exact number? I don't know but it seems to generate about the same position on summery graph that visual basics represents, and I have no idea what negative l means since it is in nano seconds.
this was an example all summery graph data is in this file and I need all of those for my program documentation
Hello @Rambod Mokhtari,
Would you mind telling me how to get such a .counters file? I consulted a lot of official documentation about .net counters, but didn't find the answer you were looking for, so I thought it might be helpful when I tried to export this file. Was this file generated by Visual Studio?
@Zhengye Xu-MSFT of course I can
in my previous answer I have posted a screen shot from 7zip that shows it in the diagsession file so I don't post anything about that to prevent repetition, but onto visual studio's configurations to make it, I can provide a step by step instructions to reproduce it, since I have already done it like trice, my visual studio is the latest version as of current visual studio 2022 17.7.4 with c++ core features, windows universal c runtime and c++ 2022 Redistributable update includes with optional installed parts of MSVC v143, C++ ATL, Just-In-Time debugger, C++ profiling tools, C++ CMake tools, Test adapter for Boost, Test Adapter for Google, IntellieCode, C++ AddressSanitizer, IntelliTrace, C++ MFC, Windows 10 SDK(10.0.20348.0), Graphics debugger and GPU profiler for DirectX, MSBuild, C# and Visual Basic Roslyn compilers, Text Template Transformation, NuGet package manager, DGML editor, Code map, Class Designer, SQL Server Express 2019 LocalDB And with profiling tool with this setting:
and there is just a thing that is not default here which is the Memory usage setting on profiling tool which is set to
and this is pretty much it, then it goes to hitting start, profiling the program and stop then crtl+s to save the diagsession file
