Patent ID: 7725777

Claim:
A method for identifying a cause for a response time problem for a transaction in a distributed computing system that includes a central server and a plurality of subsystems, where a single transaction is divided into a plurality of sub-transactions and each sub-transaction is sent to a given subsystem of the plurality of subsystems, the method comprising: storing data at each subsystem relating to sub-transactions of transactions performed by the subsystems; discovering a response time problem in connection with completion of a particular transaction; identifying each subsystem of the plurality of subsystems involved in the particular transaction; forwarding the data stored at each identified subsystem to the central server, the forwarded data including instance data relating to the sub-transaction of the particular transaction performed by the identified subsystems and aggregate data relating to sub-transactions of transactions performed by the identified subsystems; and performing a Root-Cause Analysis using the forwarded aggregate data and the forwarded instance data to identify the subsystem that caused the response time problem with the particular transaction.
