Abstract

Performance measurement systems and management applications are needed to help control and manage the performance behaviour of distributed applications. Measurement systems are responsible for efficiently collecting information about the applications and making it available for use by management applications. Efficiency requires the performance information for each application process to be aggregated on a periodic basis, before it is made accessible to management applications. As a result, errors in performance estimates for application metrics can arise when deducing performance measures for the processes and the distributed application as a whole. A loose upper bound for the worst case error is given, and a simulation study is conducted to better quantify the error for an example system. We consider the impact of this error on several different types of management applications. Lastly, a technique is presented that can be used to decrease the error without sacrificing efficiency.
