Trace Size Exceeded

Issue に示されている Django recorder と middleware の設定、およびそこからリンクされている AWS X-Ray Python 設定ドキュメントから始めてください。daemon による 50 セグメントのログエントリの繰り返しと、集中サンプリングのフォールバックメッセージを併せて確認してください。trace サイズエラーの原因を特定し、実行可能な解決策を文書化できれば完了です。

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.
