Asynchronous collection and correlation of trace and communications event data
View Patent ↗A transaction processing system that includes a communications bridge between clients and a transaction processing engine provides a way to correlate events associated with the communications bridge and events associated with the transaction processing engine. By passing a unique identification information with the transaction requests and response between the communications bridge and transaction processing engine and including the unique identification information in logging information created by each, a correlation utility may correlate logging information to create a more complete view of the events associated with a transaction, including end-to-end response times.
