Visual Studio 2017 profiler does not show function names

Question

Hi,
I ran the Profiler (Alt+F2) in Visual Studio 2017 on several projects of mine, but they all show the same thing. I get a table where under “Function Name” column, I only have the project exe name and PID number. I am running in Release mode, x64, Local windows Debugger. SDK version: 10.0.17763.0 What could be the issue and how to fix it? A simple example of a code I tested is:

#include <cstdio>

void func1()
{
	for (int i = 0; i < 1000; i++)
	{
		printf("%d\n", i);
	}
}

void func2()
{
	for (int i = 0; i < 1000; i++)
	{
		func1();
	}
}

int main()
{
	func2();
}

Hello @24206230 ,

Welcome to Microsoft Q&A forum.

I tested on my side and stopped recording after several seconds and I got following table:

Do you mean that main and printf(functions) are not listed there? Could you please share us a screenshot to confirm this issue?

Besides, which tool did you select, CPU Usage, GPU Usage, Memory Usage or …?

Currently, I suggest try following methods:

1. Reset VS settings by opening Developer Command Prompt for VS 2017 > run devenv /ResetSettings.
2. Check if there’s any setting/limitation for your machine, such as for CPU, for GPU, for Memory.
3. If you are using performance profiler on a Virtual Machine, a remote machine or something similar, then please let us know.
4. Try to create a new solution and copy your sample code to this new solution then test again, this is useful for narrowing down this issue.

Please feel free to contact us.

Sincerely,

Tianyu
