Meeting Minutes from 2012 Joint Techs in Stanford
July 16, 2012
Welcome from Ken Miller, Co-Chair of Performance Working Group

A: We used EC2, with placement in east and west coast
- final results could be averaged
- when experience server congestion, in virtual environment, spin up another one.
- looking for more in second field trial.
Q: Are you doing anything to control who can access testers?
A: No protection today
Q: Are you looking at any server data?
A: No, just client data
- curious to see if you need to do east/west thing
- Could speed up by factor of 2 if only do one.
- Any suggestions, comments, please contact

SFLOW Data Network Visibility and Control
Neil McKee, InMon Corporation

- sFlow: widely supported industry standard
- based on virtual network and switches
- monitors all protocols
- captures packet path
- senders all open source & free
- replaces counter polling
- allows you to do lots of things
- IP address, URLs, app attributes...

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
