AWS的X射线“实体不存在CallContext中”使用.NET控制台应用程序

Question

我有这样的一个SQSClient设置：

var client = new AmazonSQSClient(); 
new AWSSdkTracingHandler(AWSXRayRecorder.Instance).AddEventHandler(client); 
return client; 

现在

当我在客户端调用

var receiveResult = _amazonSqs.ReceiveMessage(_longPollRequest); 

我得到以下异常

Amazon.XRay.Recorder.Core.Exceptions.EntityNotAvailableException was 
unhandled by user code 
HResult=-2146233088 
Message=Entity doesn't exist in CallContext 
Source=AWSXRayRecorder.Core

我曾尝试添加类似AWSXRayRecorder.Instance.BeginSegment();，但不知何故，需要一个traceId，我似乎无法满足

AWSXRayRecorder.Instance.BeginSegment("ReceiveMessage", Guid.NewGuid().ToString()); 
var receiveResult = _amazonSqs.ReceiveMessage(_longPollRequest); 
AWSXRayRecorder.Instance.EndSegment(); 

例外：

我必须做一些错误，但我没有看到它。

Answer 1

您可以使用TraceId.NewId();创建新的跟踪ID。这个类在Amazon.XRay.Recorder.Core.Internal.Entities命名空间中可用。

正如Ruslan所说，我们（AWS X-Ray团队）在AWS X-Ray官方论坛上非常活跃。不幸的是，您的链接帖子似乎已发布在AWS .NET语言特定论坛中。如果他们对X-Ray specific forum进行了更改，我们更有可能快速响应未来的帖子。

感谢，
