The recent Open vSwitch 2015 Fall Conference agenda included a wide variety speakers addressing a range of topics, including: Open Network Virtualization (OVN), containers, service chaining, and network function virtualization (NFV).
The video above is a recording of the following sFlow related talk from the conference:
New OVS instrumentation features aimed at real-time monitoring of virtual networks (Peter Phaal, InMon)This talk is a follow up to an Open vSwitch 2014 Fall Conference talk on the role of monitoring in building feedback control systems.
The talk will describe the recently added packet-sampling mechanism that returns the full list of OVS actions from the kernel. A demonstration will show how the OVS sFlow agent uses this mechanism to provide real-time tunnel visibility. The motivation for this visibility will be discussed, using examples such as end-to-end troubleshooting across physical and virtual networks, and tuning network packet paths by influencing workload placement in a VM/Container environment.
Slides and videos for all the conference talks are available on the Open vSwitch web site.
