Question

我无法弄清楚如何为aspnetcore项目配置AI。我做了以下事情：

services.AddSingleton<ITelemetryInitializer, AppInsightsInitializer>();
services.AddApplicationInsightsTelemetry(Configuration);

我需要登录用户和servicename所以我有这个初始化程序：

public class AppInsightsInitializer : ITelemetryInitializer
{
    private IHttpContextAccessor _httpContextAccessor;
    public AppInsightsInitializer(IHttpContextAccessor httpContextAccessor)
    {
        _httpContextAccessor = httpContextAccessor ?? throw new ArgumentNullException("httpContextAccessor");
    }
    public void Initialize(ITelemetry telemetry)
    {
        var httpContext = _httpContextAccessor.HttpContext;
        telemetry.Context.Properties["appname"] = "MyCoolService";

        if (httpContext != null && httpContext.User.Identity.IsAuthenticated == true && httpContext.User.Identity.Name != null)
        {
            telemetry.Context.User.AuthenticatedUserId = httpContext.User.Identity.Name;
        }
    }

}

我没有applicationinights.config文件（我知道不需要它们）

问题：我每个日志有4个条目（相同的ID）。数据是正确的。我在日志中也遇到了以下错误：

我正在使用：

<PackageReference Include="Microsoft.ApplicationInsights.AspNetCore" Version="2.1.0-beta1" />
<PackageReference Include="Microsoft.AspNetCore" Version="1.1.1" />
<PackageReference Include="Microsoft.AspNetCore.Mvc" Version="1.1.2" />

Answer 1

services.AddApplicationInsightsTelemetry(Configuration);

不再需要

（假设您甚至应该在该行上获得弃用警告？）

如果你在VS2017中创建了一个asp.net核心新项目，那么AI已经存在于包引用中（虽然是2.0版本，而不是那个2.1 beta版本），并且所有的连接都已经在{{1在其他一些文件中。

如果您要移植现有的，而不是上面的program.cs行，而不是

AddApplicationInsights...

在你的应用的.UseApplicationInsights()启动中。有关详细信息，请参阅2.1 beta release notes on github

中的相关信息

我们还在努力更新VS2017中的“配置应用程序洞察”工具，以便在将来的更新中正确“迁移”这样的应用程序。

我不确定为什么你会得到任何事件的多个实例，除非你明确记录它们，或者你可能有多次启动调用（也不应该影响任何事情）。你在哪里看到多个实例？在VS的appinsights工具？在门户网站？
