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. 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. If fixed function appliances are going to be replaced by virtualized appliances the service levels, manageability and service assurance needs to remain consistent or improve on what is available today. One specific use case that needs to be supported in NFV deployments is the ability to detect and correct noisy neighbor co-tenants.
This talk will showcase how Intel Resource Director technology can be used in conjunction with Vitrage (the Root Cause Analysis service in OpenStack) to detect and correct a noisy neighbor, as a result of collaboration with the Barometer (NFVI Service Assurance) project in OPNFV.
This session will look at how to address a noisy neighbor situation. We start by detecting the noisy neighbour in an NFV/OpenStack environment with collectd. Next, notifications of this event are propagated to Vitrage, where the problem and its impact can be visualized and exported. Finally, in response to the event and the analysis relevant actions will be taken to fix these violations on the platform.
Attendees can expect to learn about:
- How to unlock additional platform events/notifications via Collectd and Vitrage.
- How Intel RDT can be used to detect a noisy neighbor using collectd and relay notifications to Vitrage.
- Notification enhancements and insights undertaken by Vitrage to essentially build a service assured NFVI
- Next steps, use cases and how the community is committed to improving OpenStack in this area
