From team discussion:

• Instrumentation will be done in statsd for both clicks to the accordion and button clicks.
• For buttons - track thumbs up and thumbs down, no need to track unclicks

Notes from team discussion:
Proving whether users are interested:

• Out of all pageviews where summaries are displayed, X% of pageviews had a summary opened?
• (if possible) Out of all users that have opened a summary once who have a session that is longer than a single page, X% of them open it again on a different page

It’s useful:

• Total number of clicks to “yes” and “no”
• “Yes” being more than “no”

Sanity

• How often do users who have downloaded the extension see a page where a summary is included
• Which articles have summaries opened for most frequently

Hi @ovasileva, I have drafted an instrumentation spec for Summarization feature, based on our discussion. As we plan to instrument using statsd, which is quite different from EventLogging. I pass it onto the engineers to evaluate its feasibility.
