Calculating a performance metric of a cluster in a virtualization infrastructure

摘要

In a computer-implemented method for calculating a performance metric of a cluster of hosts in a virtualization infrastructure a performance metric of each of a plurality of virtual machines in said virtualization infrastructure is accessing by a centralized management application of a virtualization infrastructure. The virtualization infrastructure comprises a plurality of hosts supporting the plurality of virtual machines. A performance metric of a cluster of the plurality of hosts is calculated by the centralized management application based on the performance metric of each of the plurality of virtual machines hosted by the cluster. The calculated performance metric of the cluster is transmitted to a database such that a history of performance metrics of the cluster are stored in the database.
