Azure Functions Application Insights 集成多行日志位于单独的条目中

Question

我们创建了几个 Azure 函数，每个函数在将异常记录到 Application Insights 时，都会将堆栈跟踪记录到单独的日志条目中，如下所示：

我的 Serilog 配置：

 }).ConfigureLogging((hostingContext, logging) =>
 {
     var sp = logging.Services.BuildServiceProvider();

     Log.Logger = new LoggerConfiguration()
         .MinimumLevel.Override("Microsoft", LogEventLevel.Warning)
         .MinimumLevel.Override("Worker", LogEventLevel.Warning)
         .MinimumLevel.Override("Host", LogEventLevel.Warning)
         .MinimumLevel.Override("System", LogEventLevel.Error)
         .MinimumLevel.Override("Function", LogEventLevel.Debug)
         .MinimumLevel.Override("Azure.Storage", LogEventLevel.Error)
         .MinimumLevel.Override("Azure.Core", LogEventLevel.Error)
         .MinimumLevel.Override("Azure.Identity", LogEventLevel.Error)
         .Enrich.WithProperty("Application", "Flight Data Functions")
         .Enrich.FromLogContext()
         .WriteTo.Console(LogEventLevel.Warning)
         .WriteTo.ApplicationInsights(sp.GetRequiredService<TelemetryClient>(), TelemetryConverter.Traces, LogEventLevel.Warning)
         .CreateLogger();

     logging.AddSerilog(Log.Logger, true);
 })

主机.json

{
  "version": "2.0",
  "logging": {
    "applicationInsights": {
      "samplingSettings": {
        "isEnabled": true,
        "excludedTypes": "Request"
      },
      "enableLiveMetricsFilters": true
    }
  },
  "extensions": {
    "http": {
      "routePrefix": ""
    }
  }
}

我们正在使用 Serilog：

        <PackageReference Update="Serilog" Version="4.0.1" />
        <PackageReference Update="serilog.extensions.logging" Version="8.0.0" />
        <PackageReference Update="Serilog.AspNetCore" Version="8.0.2" />
        <PackageReference Update="Serilog.Enrichers.Environment" Version="3.0.1" />
        <PackageReference Update="Serilog.Enrichers.Process" Version="3.0.0" />
        <PackageReference Update="Serilog.Enrichers.Thread" Version="4.0.0" />
        <PackageReference Update="Serilog.Settings.Configuration" Version="8.0.2" />
        <PackageReference Update="Serilog.Sinks.ApplicationInsights" Version="4.0.0" />
        <PackageReference Update="Serilog.Sinks.Async" Version="2.0.0" />
        <PackageReference Update="Serilog.Sinks.Console" Version="6.0.0" />
        <PackageReference Update="Serilog.Sinks.File" Version="6.0.0" />
        <PackageReference Update="Serilog.Sinks.Seq" Version="8.0.0" />

Answer 1

要使用 Serilog 启用日志记录，将堆栈跟踪的每一行记录为 Application Insights 和 Azure Functions 中的单独日志条目，请执行以下步骤：

添加以下内容以将整个堆栈跟踪格式化为单个日志条目。

try
{
    // Your function code that may throw an  sample exception .
}
catch (Exception ex)
{
 
    string fullExceptionDetails = $"{ex.GetType()}: {ex.Message}{Environment.NewLine}{ex.StackTrace}";
    Log.Fatal(fullExceptionDetails);
}

请参阅此文章配置Serilog以登录AzureFunctions。

在 Serilog 配置中，使用自定义转换器来控制发送到 Application Insights 的日志。更新 Serilog 配置如下：

.ConfigureLogging((hostingContext, logging) =>
{
    var sp = logging.Services.BuildServiceProvider();
    Log.Logger = new LoggerConfiguration()
        .MinimumLevel.Override("Microsoft", LogEventLevel.Warning)
        .MinimumLevel.Override("Function", LogEventLevel.Debug)
        .Enrich.WithProperty("Application", "Flight Data Functions")
        .Enrich.FromLogContext()
        .WriteTo.Console(LogEventLevel.Warning)
        .WriteTo.ApplicationInsights(
            sp.GetRequiredService<TelemetryClient>(),
            new CustomTelemetryConverter(), 
            LogEventLevel.Warning)
        .CreateLogger();
     logging.AddSerilog();
})

输出：
