Benchmarking decentralized monitoring mechanisms in peer-to-peer systems.

ABSTRACTDecentralized monitoring mechanisms enable obtaining a global view on different attributes and the state of Peer-to-Peer systems. Therefore, such mechanisms are essential for managing and optimizing Peer-to-Peer systems. Nonetheless, when deciding on an appropriate mechanism, system designers are faced with a major challenge. Comparing different existing monitoring mechanisms is complex because evaluation methodologies differ widely. To overcome this challenge and to achieve a fair evaluation and comparison, we present a set of dedicated benchmarks for monitoring mechanisms. These benchmarks evaluate relevant functional and non-functional requirements of monitoring mechanisms using appropriate workloads and metrics. We demonstrate the feasibility and expressiveness of our benchmarks by evaluating and comparing three different monitoring mechanisms and highlighting their performance and overhead.
