DATA CENTER BASED FAULT ANALYSIS METHOD AND DEVICE

摘要

Embodiments of the present invention disclose a fault analysis method based on a data center. The method includes: obtaining a topology structure diagram, where nodes in the topology structure diagram include component devices of the data center and a virtual machine running on the data center; and when a fault occurs in the data center, obtaining a fault alarm and determining, according to the topology structure diagram, whether the fault reduces communications paths between virtual machines in a virtual machine group running on the data center. In this method, actual impact of a fault on each service running on a data center can be analyzed, so as to promote accuracy of a fault analysis in the data center.
