SFLOW Data Network Visibility and Control
Neil McKee, InMon Corporation
sFlow now monitors more than just packets; there is also server instrume= ntation 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 contro=
l?
A: Better to use wildcards when possible instead of OpenFlow controls.
