RODS: General Framework for Rigorous Observation of Distributed Systems

n this work we describe a methodology for monitoring and evaluating distributed systems. This methodology is supported by a rigorous conceptual framework, whose design was made using concepts from metrology science. Cur- rent distributed systems are heterogenous systems, characterized by the usage of several kind of hardware, operating systems, middleware software, networks and so on. To support experimental evaluation and monitoring of such het- erogeneous systems, the framework here proposed is composed of a sequence of steps and a set of tools that can be used for evaluation and for monitoring of distributed systems composed of different kinds of nodes.
