使用Application API與ASP API核心

Question

社區

我遇到麻煩連接應用程序見解到我的ASP WEB API核心。 遵循標準手冊我仍然無法在我的AppInsights帳戶中找到任何記錄。 我使用了很多手冊，但它們非常相似，並描述瞭如何爲ASP Core（而不是API Core）配置App Insights。 所以我想知道是否需要一些特殊的配置（或nuget包或其他）來使AppInsights跟蹤我的API服務請求？

一旦我無法使AppInsights開箱即用，我仍然可以創建TelemetryClient的實例並手動發佈數據，但在我的情況下，這並不可取。

重要提示：我使用VS 2017年RC，網絡API核心項目（的csproj）

UPD

的csproj文件內容：

       .AddJsonFile($"appsettings.{env.EnvironmentName}.json", optional: true); 

      if (env.IsDevelopment()) 
      { 
       // This will push telemetry data through Application Insights pipeline faster, allowing you to view results immediately. 
       builder.AddApplicationInsightsSettings(true); 
      } 

      builder.AddEnvironmentVariables(); 

      Configuration = builder.Build(); 
     } 

     public IConfigurationRoot Configuration { get; } 

     // This method gets called by the runtime. Use this method to add services to the container. 
     public void ConfigureServices(IServiceCollection services) 
     { 
      services.AddMvc(); 

      services.AddApplicationInsightsTelemetry(Configuration); 
     } 

     // This method gets called by the runtime. Use this method to configure the HTTP request pipeline. 
     public void Configure(IApplicationBuilder app, IHostingEnvironment env, ILoggerFactory loggerFactory) 
     { 
      if (env.IsDevelopment()) 
      { 
       app.UseDeveloperExceptionPage(); 
      } 

      loggerFactory.AddConsole(Configuration.GetSection("Logging")); 
      loggerFactory.AddDebug(LogLevel.Trace); 
      loggerFactory.AddConsole(LogLevel.Error); 

      app.UseApplicationInsightsExceptionTelemetry(); 

      app.UseMvc(); 
     } 

Answer 1

，那麼舊的指令是錯誤的，因爲他們爲上基於xproj的asp.net核心實現。

如果您創建一個新 asp.net核心網在VS2017項目，ApplicationInsights將已經從一開始就安裝了，應該是版本：

<PackageReference Include="Microsoft.ApplicationInsights" Version="2.2.0" /> 
<PackageReference Include="Microsoft.ApplicationInsights.AspNetCore" Version="2.0.0" /> 

（或更新版本，如果ASP。網核心團隊已經在所有這些更新）

這些項目將已經應用洞察有線起來爲好，不Startup.cs（這是舊的方式），但在Program.cs中：

new WebHostBuilder() 
    ... 
    .UseApplicationInsights() // this starts up appinsights in asp.net core now 
    ... 
    .UseOtherThings(); 

，並可能在網頁模板，如：

@inject Microsoft.ApplicationInsights.AspNetCore.JavaScriptSnippet JavaScriptSnippet 

在頂部，並

@Html.Raw(JavaScriptSnippet.FullScript) 

的<head>標籤的底部內。

如果您正在從以前版本的asp遷移。網絡核心和應用程序的見解，你還必須刪除的東西，如：

@Html.ApplicationInsightsJavaScript(TelemetryConfiguration) 

從_Layout.cshtml和上面的線替換它們，你可以刪除所有線都喜歡：

應用.UseApplicationInsightsExceptionTelemetry（）;

在Startup.cs

（如果你使用的軟件包x版本，我相信這些項目將全部顯示廢棄警告爲好，因爲他們不再需要）

VS2017的官方發行說明將此信息包含在"known issues" for application insights

Answer 2

由於此問題已解決問題article

有2點我在配置錯過：
1.在的csproj應參考包「Microsoft.ApplicationInsights.AspNetCore」版本=「2.0.0-β1」
2.在類啓動，方法配置我錯過了添加app.UseApplicationInsightsRequestTelemetry（）;

當我改變上述AppInsights描述了已經開始。如果你正在使用VS2017的「新」 asp.net核心追蹤所有的請求
