Transaction middleware based application level transaction instance tracking across a composite application

摘要

Responsive to middleware for a domain processing a transaction instance at a processing point specified in transaction telemetry standards as a tracking point along a flow of the transaction instance from a requesting domain to a requestee domain, a facility of the middleware determines whether a token with correlation data comprising a unique identifier for the transaction instance available to both the requesting domain and the requestee domain is passed to the domain in compliance with transaction telemetry standards. Responsive to the facility of the middleware not detecting the token with correlation data, the token with generated correlation data accessible to the domain is generated. The facility of the middleware passes the token to at least one subsequent middleware instance of the plurality of middleware instances of the composite application along the flow of the transaction instance to uniquely identify the transaction instance.
