Tracer Debug Logs Enable Tracer debug mode. Use Datadog debug settings to diagnose issues or audit trace data. We don’t recommend enabling debug mode in production systems, because it increases the number of events that are sent to your loggers. A TCP connection must be successfully established and at least 1 byte of data must be sent by the peer for a connection to be considered (and logged as) accepted. From this point, connection handshake and negotiation proceeds as defined by the specification of the messaging protocol used, e.g. AMQP 0-9-1, AMQP 1.0 or MQTT.
