Gumshoe: Diagnosing Performance Problems in Replicated File-Systems
Replicated file-systems can experience degraded performance that might not be adequately handled by the underlying fault-tolerant protocols. We describe the design and implementation of Gumshoe, a system that aims to diagnose performance problems in replicated file-systems. Gumshoe periodically gathers OS and protocol metrics and then analyzes these metrics to automatically localize the performance problem to the culprit node(s). We describe our results and experiences with problem diagnosis in two replicated file-systems (replicated-CoreFS and BFS) using two file-system benchmarks (Postmark and IOzone).
