ABSTRACT
This chapter explains the relative importance of the measurement in relation to system reliability. Measurements are essential for knowing the quantitative value related to an entity under analysis. The system reliability and the real-time measurement and evaluation (M&E) are two faces of the same coin; that is, the concepts of the system reliability and measurement have a symbiotic relationship and they are continuously in feedback. The processing architecture based on measurement metadata is a semistructured data stream processor, which is specialized in M&E projects and it is implemented on a storm topology for real-time monitoring. The data source adapter represents the idea of gateway between the sensors and the real-time processor. The architecture collects data from heterogeneous data sources through the measurement adapter component. The standard proposes a way for characterizing the data and establishes the characteristics that are dependent on only the data itself or the system, or both.
