Flow topology of computer transactions

Abstract

A visualization of a topology of a flow of multiple transactions is generated. A first computer system receives a current transaction initiation request from a precursory transaction. The current transaction initiation request is for an initiation of a current transaction in the first computer system, and the precursory transaction is part of a flow of other transactions that are upstream from the current transaction. The current transaction initiation request contains parameter information that holds a hop count, which identifies how many computer systems have received other transaction initiation requests in the flow of other transactions, and a transaction initiation count, which identifies how many transaction initiation requests have been transmitted in the flow of other transactions. A processor generates a visualization of a topology map of the current transaction and the other transactions based on information in the parameter information from the current transaction initiation request.
