SFLOW Data Network Visibility and Control

Neil McKee, InMon Corporation

See Slides

sFlow now monitors more than just packets; there is also server instrumentation and it can be extended to applications

Why monitor everything with sFlow?
1. troubleshooting - always have context
2. putting network and server teams on same page
   (cloud services)
3. full observability required for automated control
     control theory 101.
     to automate closed loop, have to report all

Q: Is there any danger using OpenFlow features for accounting and control?
A: Better to use wildcards when possible instead of OpenFlow controls.
