ABSTRACT:
A method and apparatus for monitoring the behavior over time of a distributed system. Time-stamped data descriptive of events at one subsystem are placed into a local buffer. The subsystem is notified of the time when a trap condition occurs at another subsystem. Data having a time-stamp within a certain interval of the occurrence of the trap condition are archived to provide a history of the system for later analysis. Time is determined by a local clock in each subsystem. These clocks are synchronized to ensure accurate correlation between events at different subsystems. Trap conditions are categorized and data descriptive of subsystem states are classified to facilitate selective notification of one or more other subsystems, and selective retention of the data, depending on which category of trap condition has occurred and which class of data has been collected.
