Software-Defined Networking (SDN) and virtual environment raise new challenges for network monitoring tools. The dynamic and flexible nature of these network technologies requires adaptation of monitoring infrastructure to overcome challenges of analysis and interpretability of the monitored network traffic. This paper describes a concept of automatic on-demand deployment of monitoring probes and correlation of network data with infrastructure state and configuration in time. Such an approach to monitoring SDN & virtual networks is usable in several use cases, such as IoT networks and anomaly detection. It increases visibility into complex and dynamic networks. Additionally, it can help with the creation of well-annotated datasets that are essential for any further research.
