Team,
We are facing issues while creating a diagnostics session using the tool VSDiagnostics.exe to collect the performance data required for our analysis in Visual Studio. we use Visual Studio 2022
Command Used:
VSDiagnostics.exe start 2 /attach:5784 /loadConfig:".\AgentConfigs\CpuUsageBase.json"
Output:
C:\Program Files\Microsoft Visual Studio 17.0\Team Tools\DiagnosticsHub\Collector>VSDiagnostics.exe start 2 /attach:5784 /loadConfig:".\AgentConfigs\CpuUsageBase.json"
Microsoft (R) VS Standard Collector

2023-10-11T16:38:13.1033333+00:00 I got the above mentioned error when i copied the command VSDiagnostics.exe alone and executed it to collect the diagnostics session. But after installing visual studio on the same instance i was able to initiate a diagnostics session but i am not able to stop the session to get the dump file . Created another ticket to follow up. https://developercommunity.visualstudio.com/t/Not-able-to-stop-the-VSDiagnostics-sessi/10477062

2023-10-19T12:59:44.0566667+00:00 @Justin Smits I've found that this issue only occurs with the VS Remote tools 17.7, but 17.6 is fine. I presume that's also true for the main VS build...
