我面临的情况是，在将我所有的Serilog* nuget软件包升级到

<PackageReference Include="Serilog" Version="2.12.0" />
<PackageReference Include="Serilog.Extensions.Hosting" Version="5.0.1" />
<PackageReference Include="Serilog.Extensions.Logging" Version="3.1.0" />
<PackageReference Include="Serilog.Settings.Configuration" Version="3.4.0" />
<PackageReference Include="Serilog.Sinks.Console" Version="4.1.0" />
<PackageReference Include="Serilog.Sinks.ElasticSearch" Version="8.4.1" />
<PackageReference Include="Serilog.Sinks.Seq" Version="5.2.1" />

当我使用

Log.Logger = LoggerConfiguration()
    .ReadFrom.Configuration(config)
    .Enrich.WithElasticApmCorrelationInfo()
    .WriteTo.Elasticsearch(new ElasticsearchSinkOptions(new Uri("http://xxxxxxxxxxxxxxxxxxx"))
    {
        AutoRegisterTemplate = true,
        IndexFormat = "mslogs-{0:yyyy.MM.dd}",
        DetectElasticsearchVersion = true,
        RegisterTemplateFailure = RegisterTemplateRecovery.IndexAnyway,
        AutoRegisterTemplateVersion = AutoRegisterTemplateVersion.ESv7,
        FailureCallback = e => Console.WriteLine($"Unable to submit event {e?.RenderMessage()} to ElasticSearch. Exception : " + e?.Exception?.ToString()),
        EmitEventFailure = EmitEventFailureHandling.WriteToSelfLog |
                                EmitEventFailureHandling.WriteToFailureSink |
                                EmitEventFailureHandling.RaiseCallback,
        BufferCleanPayload = (failingEvent, statuscode, exception) =>
        {
            dynamic e = JObject.Parse(failingEvent);
            return JsonConvert.SerializeObject(new Dictionary<string, object>()
                {
                    { "action", "DeniedByElasticSearch"},
                    { "@timestamp",e["@timestamp"]},
                    { "level","Error"},
                    { "message","Error: "+e.message},
                    { "messageTemplate",e.messageTemplate},
                    { "failingStatusCode", statuscode},
                    { "failingException", exception}
                });
        },
        CustomFormatter = new EcsTextFormatter()
    })
    .CreateLogger();

使用appsettings.json配置

"Serilog": {
    "Using": [],
    "MinimumLevel": {
      "Default": "Information",
      "Override": {
        "Microsoft": "Warning",
        "System": "Information",
        "Elastic": "Warning",
        "Apm": "Warning"
      }
    },
    "WriteTo": [
      {
        "Name": "Console"
      }
    ],
    "Enrich": [
      "FromLogContext",
      "WithMachineName",
      "WithProcessId",
      "WithThreadId"
    ],
    "Properties": {
      "ApplicationName": "myapplication"
    }
  }

它抛出以下异常，显然是在调用.ReadFrom.Configuration(config)扩展方法时：

重要注意事项

• 对于两个独立的微服务来说，这是完全相同的行为，我们将软件包升级推到了生产环境中。
• 它不会在本地抛出（docker环境），也不会在开发环境中的K8S集群中抛出，或者在uat环境中也不会抛出，但是它会在生产环境中系统地抛出。
• 我们从vanilla .net运行时docker映像（mcr.microsoft.com/dotnet/sdk：6.0）系统地（提交触发）构建微服务，并使用Azure代理在Azure Devops上的CI/CD管道中动态地进行基本的. net恢复。
• 当我降级到之前版本的Serilog* 软件包时（在升级之前），在我们所有的环境中，这两个应用程序都能正常运行
• 微服务是在.net 6中开发的，它们托管在K8S集群（AKS）中，而Elasticsearch集群的版本为v 7.17.1

以下是出现问题的降级版本

<PackageReference Include="Serilog" Version="2.11.0" />
<PackageReference Include="Serilog.Extensions.Hosting" Version="5.0.1" />
<PackageReference Include="Serilog.Extensions.Logging" Version="3.1.0" />
<PackageReference Include="Serilog.Settings.Configuration" Version="3.3.0" />
<PackageReference Include="Serilog.Sinks.Console" Version="4.0.1" />
<PackageReference Include="Serilog.Sinks.ElasticSearch" Version="8.4.1" />
<PackageReference Include="Serilog.Sinks.Seq" Version="5.1.1" />
<PackageReference Include="StackExchange.Redis" Version="2.6.48" />

由于该问题仅发生在我们的生产环境中，因此我感觉Elk中的数据/设置存在问题，新的Serilog* 强调了这一点，但我不知道从何处进行调查。
