SpeedIndex attribute not supported.

[jenssvensson]

Is there any way to get the SpeedIndex attribute in the response using the command line interface?

Something like this:
webpagetest test http://staging.example.com --first --server http://<some private instance>/ --connectivity 3G --location us_east_wptdriver --poll 5 --timeout 60 > staging.json

Hey @jenssvensson you need to turn on video and you will get SpeedIndex in your result.
