Advanced monitoring of the OpenStack NFV infrastructure: A Nagios approach using SNMP

This paper is focused on evaluation of Nagios, an open-source flexible monitoring tool for enterprises, in a cloud-based network orchestrated by OpenStack. The work relies on a previous work done within UC Labs which added new objects (i.e. QoS parameters) in a management information base MIB. The solution aims at collecting the Available Transfer Rates and One-Way Delays of the links within the cloud, in order to provide the optimization of the Network Virtualization Functions.
