Note

We recommend that you use the Azure Az PowerShell module to interact with Azure. See Install Azure PowerShell to get started. To learn how to migrate to the Az PowerShell module, see Migrate Azure PowerShell from AzureRM to Az.

In this article, you learn how to run Application Insights Profiler on your Azure virtual machine (VM) or Azure virtual machine scale set via three different methods. Using any of these methods, you will:

  • Configure the Azure Diagnostics extension to run Profiler.
  • Install the Application Insights SDK onto a VM.
  • Deploy your application.
  • View Profiler traces via the Application Insights instance on Azure portal.

Enable Profiler

You can enable Profiler by any of the following three ways:

  • Within your ASP.NET Core application using an Azure Resource Manager template and Visual Studio (recommended).
  • Using a PowerShell command via the Azure CLI.
  • Using Azure Resource Explorer.

Install the Azure Diagnostics extension

  1. Choose which Azure Resource Manager template to use:

  2. In the template, locate the resource of type extension.

  3. In Visual Studio, navigate to the arm.json file in your ASP.NET Core application that was added when you installed the Application Insights SDK.

  4. Add the resource type extension from the template to the arm.json file to set up a VM or virtual machine scale set with Azure Diagnostics.

  5. Within the WadCfg tag, add your Application Insights instrumentation key to the MyApplicationInsightsProfilerSink.

"WadCfg": {
  "SinksConfig": {
    "Sink": [
      {
        "name": "MyApplicationInsightsProfilerSink",
        "ApplicationInsightsProfiler": "YOUR_APPLICATION_INSIGHTS_INSTRUMENTATION_KEY"
      }
    ]
  }
}        
  1. Deploy your application.
