Microsoft.VisualStudio.DiagnosticsHub.VSTestPerformanceCollector

VSTest DataCollectors for performance profiling during test runs, producing .diagsession files that can be analyzed in Visual Studio's Performance Profiler.

Available Collectors

  • CpuUsageCollector - CPU profiling to identify performance bottlenecks

Requirements

  • Visual Studio 2022 (17.11 or later) or Visual Studio Remote Tools must be installed
  • Windows x64

Installation

dotnet add package Microsoft.VisualStudio.DiagnosticsHub.VSTestPerformanceCollector

Usage

Create a .runsettings file with the following configuration:

<?xml version="1.0" encoding="utf-8"?>
<RunSettings>
  <DataCollectionRunSettings>
    <DataCollectors>
      <DataCollector friendlyName="CpuUsageCollector" 
                     uri="datacollector://Microsoft/CpuUsageCollector/1.0" 
                     enabled="True">
        <Configuration>
          <AttachToTestResults>true</AttachToTestResults>
        </Configuration>
      </DataCollector>
    </DataCollectors>
  </DataCollectionRunSettings>
</RunSettings>

Then run your tests:

dotnet test --settings my.runsettings

Option 2: Via CLI Argument

dotnet test --collect:"CpuUsageCollector"

Note: This uses default configuration. Custom settings require a .runsettings file.

Configuration Options

Option Type Default Description
OutputPath string TestResults folder Directory for .diagsession output
AttachToTestResults bool true Attach diagsession to test results

Analyzing Results

The .diagsession files produced by the collector can be opened with Visual Studio.
