Monitoring and measurement in software-defined infrastructure

Software-Defined Infrastructure (SDI) presents an approach for integrated management of virtualized heterogeneous resources. Monitoring and measurement is an essential component for effective control and management. This paper presents an architecture of a system, named MonArch, based on SDI that provides integrated monitoring and measurement functionalities. Unlike existing cloud and network monitoring systems, MonArch supports execution of user-generated monitoring tasks, offers monitoring as a service to tenants, administrators as well as management modules, and provides a framework for monitoring data analytics. We have implemented and deployed MonArch in the SAVI Testbed, and our experience shows the system is able to support a wide variety of monitoring tasks while achieving high performance and scalability.
