Towards Adapting System Execution Traces for Validation of Enterprise Distributed System QoS Properties

Abstract

System execution traces are useful artifacts for validating enterprise distributed software system quality-of-service (QoS) properties, such as end-to-end response time, service time, and throughput. With proper planning during development phase of the software lifecycle, it is possible to ensure such traces contain required properties to facilitate analysis for QoS validation. In some case, however, it is not possible to ensure system execution traces contain the necessary properties for QoS analysis. Consequently, this makes it hard to analyze such system execution traces for validation of QoS properties. This paper therefore presents preliminary work on the System Execution Trace Adaptation Framework (SETAF) for adapting system execution traces to support analysis of It also presents preliminary results from applying SETAF to externally developed applications. The initial results show that it is possible to validate QoS properties by adapting system execution traces at analysis time instead of modifying the application's existing source code.
