Adapting system execution traces to support analysis of software system performance properties

UNITE is a method and tool that analyzes software system performance properties, e.g., end-to-end response time, throughput, and service time, via system execution traces. UNITE, however, assumes that a system execution trace contains properties (e.g., identifiable keywords, unique message instances, and enough variation among the same event types) to support performance analysis. With proper planning, it is possible to ensure that properties required to support such analysis are incorporated in the generated system execution trace. It, however, is not safe to assume this to be the case with many existing software systems.
