azure - 如何在不依赖注入(inject)的情况下配置 TelemetryConfiguration？

Question

我在 Web 作业中使用 Application Insights。目前我不使用依赖注入(inject)。我需要配置 TelemetryChannel 以便能够在退出 webjob 之前刷新提供程序。是否可以在不使用 DI 的情况下将 TelemetryConfiguration 配置/设置/注入(inject)到 App Insights 的日志记录提供程序中？

我使用以下语句来添加日志记录提供程序。

    builder.AddApplicationInsightsWebJobs(o => o.ConnectionString = connStr).SetMinimumLevel(LogLevel.Information);

Answer 1

configure TelemetryConfiguration without dependency injection?

要在没有DI的情况下配置遥测，我们需要将Instrumentation Key或ConnectionString传递给TelemetryConfiguration。

我尝试从 appsettings.json 设置 key

安装 NuGet 包 Microsoft.ApplicationInsights.Web。

我的 appsettings.json 文件

{
  "Logging": {
    "ApplicationInsights": {
      "LogLevel": {
        "Default": "Debug",
        "Microsoft": "Error"
      }
    },
    "LogLevel": {
      "Default": "Information",
      "Microsoft.AspNetCore": "Warning"
    }
  },

  "AllowedHosts": "*",
  "ApplicationInsights": {
    "ConnectionString": "****",
    "Instrumentationkey": "****"
  }
}

谢谢@rogerpence.dev获取代码片段。

我尝试遵循给定的代码，但收到以下错误。

 var config = new ConfigurationBuilder()
.SetBasePath(Directory.GetCurrentDirectory())
.AddJsonFile("appsettings.json")
.AddEnvironmentVariables()
.Build(); 

目前，我已在 Program.cs 文件本身中设置了 key 。

Is it possible to configure/set/inject the TelemetryConfiguration into the logging provider for App Insights without DI?

在 Visual Studio 中，右键单击解决方案根文件夹 => 添加 => 连接服务。

• 添加 Application Insights 服务依赖项。

我的.csproj文件

<Project Sdk="Microsoft.NET.Sdk;Microsoft.NET.Sdk.Publish">
  <PropertyGroup>
    <OutputType>Exe</OutputType>
    <TargetFramework>net6.0</TargetFramework>
    <ImplicitUsings>enable</ImplicitUsings>
    <Nullable>enable</Nullable>
  </PropertyGroup>
  <ItemGroup>
    <PackageReference Include="Microsoft.ApplicationInsights" Version="2.21.0" />
    <PackageReference Include="Microsoft.ApplicationInsights.Web" Version="2.21.0" />
    <PackageReference Include="Microsoft.ApplicationInsights.WorkerService" Version="2.15.0" />
    <PackageReference Include="Microsoft.Extensions.Configuration" Version="7.0.0" />
    <PackageReference Include="Microsoft.Extensions.Configuration.Abstractions" Version="7.0.0" />
    <PackageReference Include="Microsoft.Extensions.Primitives" Version="7.0.0" />
  </ItemGroup>
  <ItemGroup>
    <None Update="appsettings.json">
      <CopyToOutputDirectory>Always</CopyToOutputDirectory>
    </None>
    <None Update="Settings.job">
      <CopyToOutputDirectory>Always</CopyToOutputDirectory>
    </None>
  </ItemGroup>
</Project>

我们有MSDoc其中解释了在不依赖注入(inject)的情况下配置遥测。

Program.cs

using Microsoft.ApplicationInsights;
using Microsoft.ApplicationInsights.DependencyCollector;
using Microsoft.ApplicationInsights.Extensibility;
using System.Net.Http;
using System.Threading.Tasks;
using static System.Net.Mime.MediaTypeNames;

namespace ConsoleApp
{
    class Program
    {
        static void Main(string[] args)
        {            
            TelemetryConfiguration configuration = TelemetryConfiguration.CreateDefault();
            configuration.ConnectionString = "Copy the Connectionstring from AppInsights";
            //configuration.InstrumentationKey = "****";
            var telemetryClient = new TelemetryClient(configuration);
            telemetryClient.TrackTrace("Hello World!");
            telemetryClient.TrackTrace("This is the Telemetry Logs!");
            telemetryClient.Flush();
        }      
    }
}

输出:
