c# - 带有 AppInsights 的 SeriLog 不写入 AppInsights

Question

我在 .NET CORE 2.0 项目上使用 Serilog 和 appinsights 编写日志。

我已经按如下方式配置了 SeriLog，

var loggerConfiguration = new LoggerConfiguration()
                .ReadFrom.Configuration(configuration)
                .Enrich.FromLogContext()
                .Enrich.WithDemystifiedStackTraces();

并按如下方式写入 appInsights，

 loggerConfiguration = loggerConfiguration.WriteTo.ApplicationInsightsTraces(appInsightsIntrumentationKey, serilogLevel)
.WriteTo.RollingFile(Path.Combine(contentRoot, "Logs/log-{Date}.log"), retainedFileCountLimit: 14);

我在日志文件夹中看到生成的日志，但我在 appInsights 中看不到任何内容。

我做错了什么？

我试过了as documented

    "ApplicationInsights": {
        "InstrumentationKey": "7334f234-42c9-4a1f-b35d-4969d48020d4",
        "EnableAdaptiveSampling": false,
        "EnablePerformanceCounterCollectionModule": false
    },
    "Serilog": {
        "WriteTo": [
            { "Name": "Console" },
            {
                "Name": "ApplicationInsights",
                "Args": {
                    "instrumentationKey": "7334f234-42c9-4a1f-b35d-4969d48020d4",
                    "telemetryConverter": "Serilog.Sinks.ApplicationInsights.Sinks.ApplicationInsights.TelemetryConverters.TraceTelemetryConverter, Serilog.Sinks.ApplicationInsights"
                }
            }
        ]
    }

它适用于 Azure 应用服务和开发计算机

程序.cs:

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

启动.cs

public Startup(IConfiguration configuration)
{
    Configuration = configuration;
    Log.Logger = new LoggerConfiguration().ReadFrom.Configuration(Configuration).CreateLogger();
}

示例 Controller :

    [Route("[controller]")]
    [ApiController]
    public class BadValuesController : ControllerBase
    {
        private readonly ILogger<BadValuesController> _logger;
        public BadValuesController(ILogger<BadValuesController> logger)
        {
            _logger = logger;
            _logger.LogDebug("ctor");
        }

        [HttpGet]
        public IEnumerable<WeatherForecast> GetData()
        {
            _logger.LogWarning("going to raise 6 from local app");
            throw new NotImplementedException();
        }
    }

无需重建应用程序，因为未执行任何 services.AddApplicationInsightsTelemetry();。您可以将 dll 文件复制到您的应用程序并调整配置以打开 AppInsights 登录。

但是你不have TelemetryClient instance如果没有源代码修改。因此您需要等待一段时间才能选择应用洞察日志。

我已经安装了 NuGet 包
