Distributed-systems researchers at the University of Waterloo have developed tools for capturing events, such as interprocess communication, from distributed applications and displaying them using process-time diagrams. The research work has primarily concerned development of effective techniques for dealing with large collections of processes and large numbers of events, and then exploring these techniques through prototype implementation. These techniques were originally developed primarily for use in debugging applications, but are now being examined for use in monitoring and management of applications in production. This paper describes the techniques and tools which have been developed as well as their intended use in monitoring and management.
