MICRO-LEVEL MONITORING, VISIBILITY AND CONTROL OF SHARED RESOURCES INTERNAL TO A PROCESSOR OF A HOST MACHINE FOR A VIRTUAL ENVIRONMENT

摘要

Aspects of this disclosure relate to monitoring use of shared resources to identify processes using such shared resources in a manner that may be affecting the performance of other processes. In one example, a method comprises: monitoring, by a computing device, usage metrics for a shared cache that is shared by one or more processors of the computing device; mapping the usage metrics to each of a plurality of virtual computing environments executing on the one or more processors, wherein the plurality of virtual computing environments includes a first virtual computing environment and a second virtual computing environment; determining, based on the mapped usage metrics, that the first virtual computing environment is using the shared cache in a manner that adversely affects the performance of the second virtual computing environment; and restricting, by the computing device, access to the shared cache by the first virtual computing environment.
