Abstract : Providing experimenters with deep insight about the effects of theirexperiments is a central feature of testbeds. In this paper, wedescribe Kwapi, a framework designed in the context of the Grid-5000testbed, that unifies measurements for both energy consumption andnetwork traffic. Because all measurements are taken at theinfrastructure level using sensors in power and network equipment,using this framework has no dependencies on the experiments themselves.Initially designed for OpenStack infrastructures, the Kwapi framework allowsmonitoring and reporting of energy consumption of distributed platforms. Inthis article, we present the extension of Kwapi to network monitoring, andoutline how we overcame several challenges: scaling to a testbed the size ofGrid-5000 while still providing high-frequency measurements; providing long-termloss-less storage of measurements; handling operational issues when deployingsuch a tool on a real infrastructure.

Keywords : measurement network traffic energy consumption Experimentation monitoring
