Monitoring the state of high number of running virtual machine instances is crucial for effective management of large-scale virtual environments. It provides invaluable information for system administrators about the health of the environment as well as the required information for automatic processes that are executed by a management system, such as automatic restart and load balancing of virtual machines. Doing that efficiently is important because it is a periodic task running in the background that may grab a lot of resources, thus potentially affect the performance and user experience of the management system. Consequently, improving virtual machines monitoring was at the focus of recent versions of oVirt. In this talk, Arik Hadas will present what has been done recently in oVirt in order to improve virtual machines monitoring and provide a glimpse into the on-going work in that area.
