使用Serilog和ApplicationInsights

Question

我正在尝试将Serilog日志记录与Application Insights连接起来，使用的是：Serilog Sinks

我不确定为什么它看起来根本不能记录到ApplicationInsights中，而文件记录部分却能正常工作。

这是我来自Program.cs的代码：

public static int Main(string[] args)
    {
        var config = ConfigurationHelper.GetConfiguration();
        var loggerConfiguration = new LoggerConfiguration()
             .ReadFrom.Configuration(config);
        var telemetryConfiguration = TelemetryConfiguration
               .CreateDefault();
        telemetryConfiguration.InstrumentationKey = config["ApplicationInsights:InstrumentationKey"];

        //loggerConfiguration.WriteTo.File("log-files/libtester-web-.log",
        //    outputTemplate: "[{Timestamp:HH:mm:ss} {Level:u3}] {Message:lj} {Properties:j}{NewLine}{Exception}",
        //    rollingInterval: RollingInterval.Day);

        Log.Logger = loggerConfiguration
            .WriteTo.ApplicationInsights(telemetryConfiguration, TelemetryConverter.Events)
            .ReadFrom.Configuration(config)
            .Enrich.WithMachineName()
            .Enrich.WithProcessId()
            .Enrich.FromLogContext()
            .CreateLogger();

        try
        {
            Log.Information("Starting web host");
            CreateHostBuilder(args).Build().Run();
            return 0;
        }
        catch (Exception ex)
        {
            Log.Fatal(ex, "Host terminated unexpectedly");
            return 1;
        }
        finally
        {
            Log.CloseAndFlush();
        }
    }

    public static IHostBuilder CreateHostBuilder(string[] args) =>
       Host.CreateDefaultBuilder(args)
           .ConfigureWebHostDefaults(webBuilder =>
           {
               webBuilder.UseStartup<Startup>();
           })
           .UseSerilog();

Appsettings.json中的相应部分：

  "Serilog": {
"Using": [
  "Serilog.Sinks.ApplicationInsights"
],
"MinimumLevel": {
  "Default": "Debug",
  "Override": {
    "Microsoft": "Information"
  }
},
"WriteTo": [
  {
    "Name": "ApplicationInsights",
    "Args": {
      "restrictedToMinimumLevel": "Information",
      "telemetryConverter": "Serilog.Sinks.ApplicationInsights.Sinks.ApplicationInsights.TelemetryConverters.TraceTelemetryConverter, Serilog.Sinks.ApplicationInsights"
    }
  },
  {
    "Name": "File",
    "Args": {
      "path": "log-files/libtester-web-.log",
      "outputTemplate": "[{Timestamp:HH:mm:ss} {Level:u3}] {Message:lj} {Properties:j}{NewLine}{Exception}",
      "rollingInterval": "Day",
      "shared": true
    }
  }
],
"Enrich": [ "FromLogContext" ],
"Properties": {
  "Application": "LibTester.Web"
}

}

它可以很好地将日志记录到日志文件目录中，但是我在AppInsights中的资源没有得到相同的日志。

我在输出中添加了以下两条消息：'Serilog.Debugging.SelfLog.Enable(msg => Debug.WriteLine(msg));‘

Answer 1

请尝试在appsettings.json中删除此分区

  {
    "Name": "ApplicationInsights",
    "Args": {
      "restrictedToMinimumLevel": "Information",
      "telemetryConverter": "Serilog.Sinks.ApplicationInsights.Sinks.ApplicationInsights.TelemetryConverters.TraceTelemetryConverter, Serilog.Sinks.ApplicationInsights"
    }
  },

删除后，我可以看到日志在azure门户->应用程序洞察中。

下面是我测试中的appsettings.json：

{
  "Logging": {
    "LogLevel": {
      "Default": "Information",
      "Microsoft": "Warning",
      "Microsoft.Hosting.Lifetime": "Information"
    }
  },
  "AllowedHosts": "*",
  "ApplicationInsights": {
    "InstrumentationKey": "xxxxxxxxx"
  },
  "Serilog": {
    "Using": [
      "Serilog.Sinks.ApplicationInsights"
    ],
    "MinimumLevel": {
      "Default": "Debug",
      "Override": {
        "Microsoft": "Information"
      }
    },
    "WriteTo": [    
      {
        "Name": "File",
        "Args": {
          "path": "log-files/libtester-web-.log",
          "outputTemplate": "[{Timestamp:HH:mm:ss} {Level:u3}] {Message:lj} {Properties:j}{NewLine}{Exception}",
          "rollingInterval": "Day",
          "shared": true
        }
      }
    ],
    "Enrich": [ "FromLogContext" ],
    "Properties": {
      "Application": "LibTester.Web"
    }
   }
  }
