Computers generate trace files containing reports on system performance, status, and faults. To analyze these trace files more efficiently, we have developed a graphical technique embodied in an interactive system for displaying large trace files. Our system uses abstraction, color, aggregation, filtering, interaction, and a drill-down capability to find patterns among the reports. We apply our...
