"Precision-Integrated Scalable Monitoring"

Navendu Jain, University of Texas

...In this talk, I will define precision as a new unified abstraction to realize the goal of system introspection. I will first present our work on designing and building PRISM, a scalable monitoring service that makes precision a first-class abstraction. PRISM quantifies (im)precision along a three-dimensional vector: arithmetic imprecision (AI) and temporal imprecision (TI) balance precision against monitoring overhead while network imprecision (NI) addresses the challenge of providing consistency guarantees despite failures. Then, I will describe how our implementation addresses the challenge of providing these metrics while scaling to a large number of nodes and attributes. Finally, I will demonstrate how the unified precision abstraction enables new monitoring applications by presenting experiences from three applications we have built.
