辅助服务中的事件登录未发布到 Azure Application Insight

Event log in in worker service not published to Azure Application Insight

我正在构建一个 Worker Service 作为 Windows Service。我使用 EventLog 进行记录。我还想添加 ApplicationInsights 来记录事件。我遵循这篇文章 https://docs.microsoft.com/en-us/azure/azure-monitor/app/worker-service ,使用 Nuget 安装 SDK 并按要求设置所有内容。这是我的 program.cs 配置。

public static IHostBuilder CreateHostBuilder(string[] args) =>
        Host.CreateDefaultBuilder(args)                
            .ConfigureServices((hostContext, services) =>
            {
                services.AddHostedService<Worker>();
                services.AddApplicationInsightsTelemetryWorkerService();
                services.CustomeDependencyInjection();
            })
            .UseWindowsService()
            .ConfigureLogging(logging =>
            {
                logging.AddEventLog(eventLogSetting =>
                {
                    eventLogSetting.LogName = "MyTestEventLog";
                    eventLogSetting.SourceName = "MyTestEventApp";
                });
            });

这是 appsetting.json 文件

{
  "ApplicationInsights": {
      "InstrumentationKey": "bd******-****-****-****-***********b"
  },
  Logging": {
    "LogLevel": {
    "Default": "Information",
    "Microsoft": "Information",
    "Microsoft.Hosting.Lifetime": "Information"
    },
    "EventLog": {
      "LogLevel": {
      "Default": "Information",
      "Microsoft": "Information",
      "Microsoft.Hosting.Lifetime": "Information"
      }
    }
  }
}

这是 worker.cs 文件中的日志记录示例

public Worker(ILogger<Worker> logger, TelemetryClient tc)
{
        _logger = logger;
        this.tc = tc;
 }
 public Task StartAsync(CancellationToken cancellationToken)
 {
        this._logger.LogInformation("In Start");
        using (tc.StartOperation<RequestTelemetry>("Operation"))
        {
            /** 
                my service starting code 
            **/
            this._logger.LogInformation("Service is being started");
            tc.TrackEvent("Worker service starting operation completed.");
        }
        this._logger.LogInformation( "Service Started");
        return Task.CompletedTask;
 }

当我运行应用程序时,我可以看到一个customEvent。我还可以看到 request 事件。但是我在 trace 中找不到任何我期望使用 _logger 发送的信息。我检查了输出 window,也没有发现针对 _logger.LogInformation.

发送了任何遥测数据

我在这里做错了什么以及如何让 ApplicationInsights 可以使用记录器信息?还是我没找对地方?

Application Insight 默认使用 Warning 作为日志级别。由于您正在使用级别 Information 进行跟踪,因此您需要使用 appsettings.json 文件配置应用程序洞察:

{
  "ApplicationInsights": {
      "InstrumentationKey": "bd******-****-****-****-***********b"
  },
  "Logging": {
    "LogLevel": {
      "Default": "Information",
      "Microsoft": "Information",
      "Microsoft.Hosting.Lifetime": "Information"
    },
    "ApplicationInsights": {
      "LogLevel": {
        "Default": "Information"
      }
    }
    "EventLog": {
        "LogLevel": {
        "Default": "Information",
        "Microsoft": "Information",
        "Microsoft.Hosting.Lifetime": "Information"
      }
    }
  }
}
