FINDING RESOURCE BOTTLENECKS WITH LOW-FREQUENCY SAMPLED DATA

摘要

A method for automatically gauging a benefit of a tuning action. The method including collecting a plurality of observations of a running state of a plurality of threads in a computer system, as executed by a processing in a computer system. Identifying a plurality of resources the computer system and a capacity of each resource of the plurality of resources. Mapping an observation of the running state of each thread of the plurality of threads to a resource that the observation of each thread uses, respectively. Applying the tuning action to a first resource of the plurality of resources to determine an impact on the performance of the computer system.
