Application Insights 有指标和依赖关系，但没有信息跟踪

问题描述

我有一个 ASP net 5。我看不到我的自定义跟踪，但我可以看到指标和依赖项 我认为这是 LogLevel 的问题，但似乎我找不到正确的设置：

Startup.cs

        public void ConfigureServices(IServiceCollection services)
        {
            services.AddControllersWithViews();
            services.AddApplicationInsightsTelemetry(Configuration["ApplicationInsights:ConnectionString"]);
        }

appsettings.json

 

     "Logging": {
        "LogLevel": {
          "Default": "Information","Microsoft": "Information","Microsoft.Hosting.Lifetime": "Information"
        }
      },"AllowedHosts": "*","ApplicationInsights": {
        "LogLevel": {
          "Default": "Information","Microsoft": "Information"
        },"ConnectionString": "InstrumentationKey=*****;IngestionEndpoint=https://westeurope-5.in.applicationinsights.azure.com/"
      },

代码：

        public async Task SendMessageAsync()
        {
            ...
            using (this._logger.BeginScope(nameof(SendMessageAsync)))
            {
                ...
                _logger.LogInformation($"Message sent...");
                ...
            }
         }

在 VS 输出中，我看到正在记录信息 msg，但没有看到 LogInformation 的 AppInsights 遥测

SenderApp.Controllers.HomeController: Information: Message sent...
Application Insights Telemetry: {"name":"AppDependencies","time":...
Application Insights Telemetry: {"name":"AppDependencies","time":...

解决方法

答案很简单，但不容易调试。

appsettings.josn 中 AppInsights 的日志记录设置应位于 Logging

     "Logging": {
        "LogLevel": {
          "Default": "Information","Microsoft": "Information","Microsoft.Hosting.Lifetime": "Information"
        },"ApplicationInsights": {
          "LogLevel": {
            "Default": "Information","Microsoft": "Information"
          }
        }
      },"ApplicationInsights": {
        "ConnectionString": "InstrumentationKey=*****;IngestionEndpoint=https://westeurope-5.in.applicationinsights.azure.com/"
      }
