Trace Size Exceeded

Bắt đầu với cấu hình Django recorder và middleware được hiển thị trong issue, cùng với tài liệu cấu hình AWS X-Ray Python mà issue liên kết đến. Xem xét các mục nhật ký 50 segment lặp lại của daemon cùng với thông báo fallback của việc lấy mẫu tập trung; công việc được hoàn tất khi xác định được nguyên nhân của lỗi kích thước trace và ghi lại một giải pháp có thể thực hiện.

Hi,

I am starting to see this error a lot in most of our django applications.

 [Error] Unprocessed segment: {	
	ErrorCode: "InvalidSegment",	
	Id: "xxxxxxxxxxxxxxxxxx",	
	Message: "Trace Size Exceeded. Reduce the number of segments per trace and the size of your segment documents."	
}

Also, whilst looking at the logs:

It looks like a lot of segments are being sent while nothing is really happening on the django application itself.

We are running the daemon on the alongside the django application, in the same docker container. We have the recorder setup as instructed here:

XRAY_RECORDER = {
    "AUTO_INSTRUMENT": True,
    "AWS_XRAY_CONTEXT_MISSING": "LOG_ERROR",
    "AWS_XRAY_TRACING_NAME": f"{env('PARTNER', default='embed')}-{env('ENVIRONMENT_TYPE')}",
    "PLUGINS": ("EC2Plugin", "ECSPlugin"),
    "AWS_XRAY_SDK_ENABLED": env("AWS_XRAY_SDK_ENABLED", default=False),
}

I am also seeing this when the application starts:

[INFO] No effective centralized sampling rule match. Fallback to local rules.

Our sampling rules are not local tho, but defined in the xray we console.
