Performing monitoring and migration of virtual machines in a data center to prevent service level degradation due to the load imposed by the monitoring

摘要

The present disclosure relates to a method for monitoring virtual machines in a data center, to a computer program for executing the method, to a monitoring control unit for monitoring virtual machines in a data center, as well as to a data center comprising the monitoring control unit. The method comprises: receiving (S502) a request to monitor a target virtual machine executing on a target computing unit hosted in the data center; identifying (S504) a current allocation of one or more virtual machines to one or more computing units hosted in the data center; determining (S506) an enhanced allocation of the one or more virtual machines to one or more computing units hosted in the data center, the enhanced allocation reducing a load imposed on the target computing unit compared to the load imposed on the target computing unit under the current allocation; migrating (S508) the one or more virtual machines so as to reallocate the one or more virtual machines from the current allocation to the enhanced allocation; and monitoring (S510) the target virtual machine upon completion of the migration of the one or more virtual machines.
