The interaction network : a performance evaluation tool for loosely-coupled distributed systems (1991)
For users of loosely-coupled distributed systems, questions about "performance" commonly involve interactive performance. The problem of measuring components of interactive response times is approached by representing the processing needed for each interaction as a graph called an interaction network. The critical path through an interaction network shows the sequence of steps that take the longest time to execute. The goal of improving performance is presented as requiring strategies to shorten the lengths of critical paths. To identify these strategies, we augment each interaction network with vertices that represent additional events of interest to a performance analyst. A particular aim has been a unified approach that treats all types of system resource (hardware, software, or data) in a consistent fashion. An example is given to show that a set of event recorders can be designed to provide measurements for an exhaustive decomposition of response times for selected sets of interactions. Finally, details are given of experimental work done to record and analyse interaction networks.

Ashton, Paul James; Penny, J. P. (University of Canterbury. Dept. of Computer Science, 1990)Measuring the interactive performance of a loosely-coupled distributed system is a difficult task. Work for a single user is spread across many computers, and there is no global time-base available for time-stamping event ...
The interaction network : a performance measurement and evaluation tool for loosely-coupled distributed systems Ashton, Paul (University of Canterbury. Computer Science, 1992)Much of today's computing is done on loosely-coupled distributed systems. Performance issues for such systems usually involve interactive performance, that is, system responsiveness as perceived by the user. The goal of ...
