But, perhaps most importantly, the monitoring fabric must be conducive to programmability, automation and integration with monitoring tools. In order to attain this, an open platform built with APIs should allow applications, whether inherent or developed by third-party software developers, to orchestrate the monitoring policies of the organization within the fabric.
For hosting organizations, a unified monitoring fabric enables the possibility to orchestrate Visibility as a Service for customers. The ability to turn up new monitoring services dynamically without manual intervention helps minimize reactive management of the infrastructure and move toward more proactive management.
When you taken into account all of these requirements, it is clear it will take centralized management, an open framework for automation and programmability, and targeted applications to provide just-in-time responsiveness to real-time events that occur within the network. Networks are already dynamic enough with virtualization, application and device mobility, and cloud deployments; SDN will only add to the problems associated with monitoring. Therefore, a monitoring fabric that's just as dynamic is required to maintain visibility.
The architecture required to build that agility looks a lot like SDN, but constructed for the tools; a unified monitoring fabric for software-defined monitoring.
The deployment of a unified monitoring fabric should ease concerns regarding the adoption of SDNs in production networks by alleviating the monitoring headache. It should deliver pervasive visibility into software-defined networks, physical networks, and virtual networks. Pervasive visibility is essential as it enables the unification of data visibility across network architectures and topologies, including virtual networks, resulting in a safe deployment within a multi-tenant setting and ultimately ensuring that SDN becomes a reality and delivers on its promise.
