The Roundtrip

Example: Client -> Proxy -> AMQP

TransactionID Received By Web Proxy API Publish To AMQP

TransactionID-<UUID> <in_millisecond> <in_millisecond>

TransactionID-<UUID> <in_millisecond> <in_millisecond>

Example - Service <-> AMQP

ServiceID PulledFromAMQP Processed PostedToAMQP

DeliveryService <in_millisecond> <in_millisecond> <in_millisecond>

NotifService <in_millisecond> <in_millisecond> <in_millisecond>

Example - Service -> ThirdParty

ThirdParty Latency
