如何通过 NLog 在 AppInsights 中获取范围信息？

Question

在构造函数中注入ILogger<> 的方法中考虑以下代码：

using (_logger.BeginScope("Requesting {page} for {identification}", page, identification))
{
    if (identification == null)
    {
        var test = "Test String";
        _logger.LogTrace("No identification present {test}. Presenting Index page", test);
        return Page();
    }

    _logger.LogDebug("Identification present: {identification}", identification);
}

我在 AI 中看到了这一行：

我希望获得有关范围的一些信息；虽然我不知道它是什么样子，但我认为它是沿着 LoggerName 和 test 属性添加到 CustomDimensions 中的。

在我的创业课程中，我有这个：

public void ConfigureServices(IServiceCollection services)
{
    services.Configure<ApplicationInsightsServiceOptions>(Configuration.GetSection("ApplicationInsights"));
    services.AddApplicationInsightsTelemetry();
    LogManager.Configuration = new NLogLoggingConfiguration(Configuration.GetSection("NLog"));

    /// ... the reset
}

我的 appsettings.json 看起来像这样：

{
  "Logging": {
    "IncludeScopes": true,
    "NLog": {
      "IncludeScopes": true
    },
    "LogLevel": {
      "Default": "Trace",
      "Microsoft": "Warning",
      "Microsoft.Hosting.Lifetime": "Information"
    },
    "ApplicationInsights": {
      "IncludeScopes": true,
      "LogLevel": {
        "Default": "Trace"
      }
    }
  },
  "NLog": {
    "autoReload": true,
    "throwConfigExceptions": true,
    "internalLogLevel": "trace",
    "internalLogFile": "${basedir}/internal-nlog.txt",
    "extensions": [
      {
        "assembly": "Microsoft.ApplicationInsights.NLogTarget"
      }
    ],
    "targets": {
      "aiTarget": {
        "type": "ApplicationInsightsTarget"
      },
      "logconsole": {
        "type": "ColoredConsole"
      }
    },
    "rules": [
      {
        "logger": "*",
        "minLevel": "Trace",
        "writeTo": "aiTarget, logconsole"
      }
    ]
  }

我有什么遗漏的吗...？

我想你可以试试这个：

    "targets": {
      "aiTarget": {
        "type": "ApplicationInsightsTarget",
        "contextproperties": [
        {
            "name": "scopecontext",
            "layout": {
                "type": "JsonLayout",
                "includemdlc": "true"
            }
        }]
      },
      "logconsole": {
        "type": "ColoredConsole"
      }
    },
