Performance estimation method for virtualized building facilities monitoring applications
Yu Kaneko, Toshio Ito, Takahiro Hara · 2017
In a remote building management system (BMS) that manages facilities of buildings, there is an application called a crawler that measures statuses of facilities via a network. By running a crawler on a Virtual Machine (VM) for each building owner, the number of Physical Machines (PMs) in the remote BMS can be reduced. However, running multiple crawlers on the same PM causes measurement time fluctuation, which may results in inaccurate monitoring and control of facilities. We propose an estimation method for measurement time accuracy of crawlers according to simulation with a model of crawlers, VMs, and PMs. The relationship between the number of crawlers running on the same PM and their measurement time accuracy can be determined by the proposed method. We verify the estimation accuracy of the proposed method by comparing with measurement time accuracy of real machines.
