Why did we build HostView?

1

Goal: Automatically detect network performance disruptions as perceived by end-users

Performance of any networked application Only performance disruptions that affect end-users

HostView: Collect network traces from end-hosts annotated with user feedback

HostView data collection

  • Network performance

– Packet headers (anonymized IP source)

  • User environment and system performance

– CPU load, OS, time zone, country

  • Application-level context

– Content-type for HTTP responses – Application (process names)

  • User feedback

– System-triggered questionnaires (3 times a day) – I’m annoyed button

Recruiting volunteers

  • Publicity

– Leaflets at IMC 2010 – CS Mailing lists in November 2010

  • Incentives

– 50 USD Amazon gift cards – Real-time feedback about network connection

HostView user feedback detailed

7

  • “I am annoyed” button

– Click when a networked application is misbehaving

  • Experience sampling mechanism (ESM)

– Fill in a questionnaire about your network connection

at most three times a day

  • Rate internet speed from 1 to 5
  • List applications if any that experienced network problems
  • Additional comments in free-from text box

Challenges

  • HostView performance

– Trace upload when user connection is slow

  • Adaptive upload algorithm

– CPU

  • Changed HostView startup mechanism
  • User feedback

– Pop-ups are distracting

  • Bypass when network connection is good
  • Disable questionnaires, just use “I am annoyed” button
