In this paper we present the design and implementation of a management system that uses server-attached wireless sensors to create an auto-configuring wireless-only monitoring network that can be used to address a number of challenges in the area of data center operations management. We exhibit the use of this wireless network in tracking the physical location of servers and in troubleshooting connectivity problems in the wired data center network infrastructure. Our system is implemented as an extension to the Nagios distributed monitoring and management system and demonstrated to provide continuous awareness of the physical location of the server infrastructure as well as insight into wired network partitions under switch failures.

Challenges include lack of support for heterogeneous Cloud providers; limited matchmaking between application requirements and Cloud capabilities; lack of meaningful cross-platform Cloud resource descriptions; lack of lifecycle management of Cloud applications; inadequate cross-layer monitoring and adaptation based on event correlation; and others. In this paper we propose solutions to these challenges and highlight the expected benefits in the context of a complex distributed application.
