As CoSP’s accelerate their adoption of SDN and NFV technologies, the increased need for metrics, performance measurement and benchmarking becomes a focus, to ensure the continued delivery of “best in class” services. As NFV environments have grown in size and complexity, the tools required to gain this greater visibility into the NFVi need to continue to evolve to meet the requirements for manageability, serviceability and resiliency.

Using Collectd as a metrics collection tool, OPNFV Barometer monitors the performance of the NFVi resources and has the capability to expose these insights via open industry standard interfaces to analytics or MANO components for potential enforcement or corrective actions. Barometer works with related open source technologies and communities (collectd, DPDK, OpenStack, Prometheus, SAF, etc.) to provide numerous metrics and events that address various different use cases such as service healing, power optimization and ensuring application QoS.

The OPNFV community has developed a comprehensive set of open source test tools and test methodologies for NFVIs and VM-based cloud platforms. With the proliferation of cloud native and edge computing, we need to think about how to evolve these tools to meet the requirements of emerging and future use cases. In this talk, we will give an outlook on how the OPNFV test tool ecosystem can address new use cases and challenges. The test tools in OPNFV are not just for NFV, but can be more widely useful. We will present the tools, and discuss how they can be extended to support new and existing usecases.

This talk is aimed at an audience that want to test their SDN/NFV deloyments (but not necessarily using OPNFV). It will give an overview of the test tools, and how they can be use tools for many different deployments, test different components of your system (VIM, vswitch, storage, etc.) and perform different types of testing (infrastructure verification, feature validation, stress and resiliency testing, performance benchmarking, characterization, etc.).

If fixed function appliances are going to be replaced and complemented by a mix of physical and virtualized appliances, the manageability and service assurance capabilities need to remain consistent or improve on what is available today. The ability to monitor the Network Function Virtualization Infrastructure (NFVI) where VNFs are in operation will be a key part of Service Assurance within an NFV environment.

It is vital to monitor systems for malfunctions that could lead to users' application service disruption and promptly react to these fault events to facilitate improving overall system performance and user experience. The relevant events and metrics must be reported to higher level fault management systems, to detect violations (and enforce SLAs), as well as faults or degradation in the performance of NFVI resources.

Additional statistics facilitate more resilient and performant telco/NFV clouds. By exposing system statistics to collectd, there is more data available, which can be used for monitoring, performance analysis, fault detection, failure prediction, etc. using OPNFV, action can then be taken to negate the effects of any faults in the deployment.

This talk will include: - a short overview of the Barometer (NFVI Service Assurance) project in OPNFV - A demo of how quickly you can start monitoring the NFVI with Barometer. - How OPNFV and ONAP are taking these changes on board
