A method of monitoring a computer application executed on a computer system. The method includes the steps of (1) without predefining events describing potential stages of a transaction executed by the computer application, using an application program interface to add software code to the computer application for assigning a single general reference to characteristic transactional information associated with the transaction, (2) using the single general reference to identify transaction events performed by the computer application in executing the transaction, and (3) measuring transaction events.

Computer system performance monitoring using transaction latency data

An application program interface (API) for use in monitoring a computer application executed on a computer system. The API includes software code added to the computer application for assigning a single general reference to characteristic transactional information associated with a transaction to be executed by the computer application. The API further includes an agent for marking the time at which the software code is executed and tagging that time with the characteristic transactional information as the characteristic transactional information is being currently processed by the computer application. The API and its method of operation provide precise measurement of the latency of information flowing through the computer system while being uncomplicated in design and implementation, minimally invasive, and highly scalable.
