C# .NET Core 中的 Azure 应用程序见解

Question

我正在使用为我的应用程序配置的 Application Insights。您可以参考这个文档ApplicatioInsight

这是我的代码：

static TelemetryConfiguration telemetryConfiguration = new TelemetryConfiguration();

public static IHostBuilder UseSerilogCreateHostBuilder(string[] args) =>
     Host.CreateDefaultBuilder(args)
         .ConfigureWebHostDefaults(webBuilder =>
         {
            
              telemetryConfiguration.ConnectionString = configuration["ApplicationInsights:ConnectionString"];                                   
              telemetryConfiguration.SetAzureTokenCredential(new DefaultAzureCredential());
              webBuilder.UseStartup<Startup>();
         })
       .UseSerilog((hostingContext, loggerConfiguration) => loggerConfiguration
             .ReadFrom.Configuration(hostingContext.Configuration)
             .WriteTo.ApplicationInsights(telemetryConfiguration, TelemetryConverter.Traces));

在 Application Insights 仪表板中，正在记录响应代码。错误响应代码（500、401 和 400）及其计数可见，但没有显示这些错误的详细描述。

这是截图：

预期失败或事务日志计数以及描述。

我创建了一个示例

ASP.NET core 8.0

应用程序并成功配置了身份验证，可以毫无问题地查看跟踪及其详细描述。

确保安装以下软件包的最新版本。

Serilog
Serilog.Sinks.Console
Serilog.Sinks.ApplicationInsights

我的program.cs：

using Microsoft.AspNetCore.Authentication.OpenIdConnect;
using Microsoft.Identity.Web;
using Serilog;
using Serilog.Sinks.ApplicationInsights;

var builder = WebApplication.CreateBuilder(args);
Log.Logger = new LoggerConfiguration()
    .MinimumLevel.Debug().
    .WriteTo.Console() 
    .Enrich.FromLogContext()   .WriteTo.ApplicationInsights(builder.Configuration["ApplicationInsights:ConnectionString"], TelemetryConverter.Traces)
    .CreateLogger();
builder.Host.UseSerilog(); 
builder.Services.AddControllersWithViews();
builder.Services.AddRazorPages();
builder.Services.AddAuthentication(OpenIdConnectDefaults.AuthenticationScheme)
.AddMicrosoftIdentityWebApp(builder.Configuration.GetSection("AzureAd"));
builder.Services.AddApplicationInsightsTelemetry();
var app = builder.Build();

if (app.Environment.IsDevelopment())
{
    app.UseDeveloperExceptionPage();
}
else
{  
    app.UseExceptionHandler(errorApp =>
    {
        errorApp.Run(async context =>
        {
            context.Response.StatusCode = 500;
            context.Response.ContentType = "text/html";
            var exceptionHandlerPathFeature = context.Features.Get<Microsoft.AspNetCore.Diagnostics.IExceptionHandlerPathFeature>();
            var exception = exceptionHandlerPathFeature?.Error;
       
            Log.Error(exception, "An unhandled exception occurred.");           
            await context.Response.WriteAsync("<h1>Something went wrong.</h1>");
        });
    });
    app.UseHsts();
}
app.UseHttpsRedirection();
app.UseStaticFiles();
app.UseRouting();
app.UseAuthentication(); 
app.UseAuthorization();  
app.UseEndpoints(endpoints =>
{
    endpoints.MapControllerRoute(
        name: "default",
        pattern: "{controller=Home}/{action=Index}/{id?}");
    endpoints.MapRazorPages();
});
var logger = Log.ForContext("SourceContext", "Startup");
logger.Information("Application started successfully."); 
app.Run();

成功验证我的应用程序

在我的应用程序洞察中，我可以查看痕迹及其详细描述。
