SFLOW Data Network Visibility and Control
Neil McKee, InMon Corporation
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
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.
