Serilog 不會將日志寫入 AWS Elasticsearch Service

Question

我正在使用 Serilog 將日志寫入我的 .NET Core 應用程序中的AWS Elasticsearch Service ，但是在登錄 Kibana 時我沒有看到任何寫入的日志。

public Startup(IConfiguration configuration, IHostingEnvironment hostingEnvironment)
{
    const string esUrl = "https://aws-es-thinger.us-west-1.es.amazonaws.com";
    Log.Logger = new LoggerConfiguration()
        .Enrich.FromLogContext()
        .Enrich.WithExceptionDetails()
        .WriteTo.Elasticsearch(new ElasticsearchSinkOptions(new Uri(esUrl))
        {
            ModifyConnectionSettings = conn =>
            {
                var httpConnection = new AwsHttpConnection("us-east-1");
                var pool = new SingleNodeConnectionPool(new Uri(esUrl));
                var conf = new ConnectionConfiguration(pool, httpConnection);
                return conf;
            },
            AutoRegisterTemplate = true
        }).CreateLogger();
}

我能夠使用HttpClient成功獲得響應。

此外，我還可以從瀏覽器加載 Kibana 和 ElasticSearch 網址。 請幫我解決我在這里缺少的東西。

編輯在啟動時連接時出現以下錯誤：

System.Net.Http.WinHttpException：無法建立與服務器的連接

我需要在連接設置中提供 AWS 訪問密鑰和秘密密鑰才能使其工作如下：

Log.Logger = new LoggerConfiguration()
.Enrich.FromLogContext()
.Enrich.WithExceptionDetails()
  .WriteTo.Elasticsearch(new ElasticsearchSinkOptions(new Uri(awsSettings.ElasticSearchUrl))
  {
      ModifyConnectionSettings = conn =>
      {
          var httpConnection = new AwsHttpConnection(awsSettings.Region
              , new StaticCredentialsProvider(new AwsCredentials
              {
                  AccessKey = awsSettings.AccessKey,
                  SecretKey = awsSettings.SecretKey,
              }));
          var pool = new SingleNodeConnectionPool(new Uri(awsSettings.ElasticSearchUrl));
          var conf = new ConnectionConfiguration(pool, httpConnection);
          return conf;
      },
      ConnectionTimeout = new TimeSpan(0, 10, 0),
      IndexFormat = "xxxxx-{0:yyyy.MM}",
      FailureCallback = e => Console.WriteLine("Unable to submit event " + e.MessageTemplate),
      EmitEventFailure = EmitEventFailureHandling.WriteToSelfLog |
           EmitEventFailureHandling.WriteToFailureSink |
           EmitEventFailureHandling.RaiseCallback,
      FailureSink = new LoggerConfiguration().WriteTo
      .RollingFile(new JsonFormatter(), "XXXXX-{Date}.txt").CreateLogger()
  })
.CreateLogger();

希望，它可以幫助將來的某個人。
