Sieve [PDF]

open access: yesProceedings of the 18th ACM/IFIP/USENIX Middleware Conference, 2017
Major cloud computing operators provide powerful monitoring tools to understand the current (and prior) state of the distributed systems deployed in their infrastructure. While such tools provide a detailed monitoring mechanism at scale, they also pose a significant challenge for the application developers/operators to transform the huge space of ...
