Trace Size Exceeded

Iniziare dalla configurazione di Django recorder e middleware mostrata nell’issue e dalla documentazione sulla configurazione di AWS X-Ray Python a cui rimanda. Esaminare le voci di log ripetute da 50 segmenti del daemon insieme al messaggio di fallback del campionamento centralizzato; il lavoro è completato quando viene identificata la causa dell’errore relativo alle dimensioni della trace e viene documentata una risoluzione attuabile.

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.
