Abstract

Naive statistics counters that are commonly used to monitor system events and performance become a scalability bottleneck as systems become larger and more NUMA; furthermore some are so inaccurate that they are not useful. We present a number of techniques to address these problems, evaluating solutions in terms of performance, scalability, space overhead, and accuracy.
