Sampling

The sampling rate and oversampling mechanisms for this instrumentation are as follows:

WikiEditor (JS and PHP):

• Default: 6.25% of all editing sessions
• arwiki, bnwiki, frwiki, hewiki, htwiki, jawiki, kowiki, viwiki, zhwiki: 20% of all editing sessions (see https://phabricator.wikimedia.org/T309260)
• 100% when the user clicks a suggested edit card on their newcomer homepage

DiscussionTools (JS):

• Default: 6.25% of all pageviews
• arwiki, bnwiki, frwiki, hewiki, htwiki, jawiki, kowiki, viwiki, zhwiki: 20% of all pageviews
• 100% when the user clicks a suggested edit card on their newcomer homepage
• 100% when $wgDTSchemaEditAttemptStepOversample is truthy

Note well that $wgDTSchemaEditAttemptStepOversample is truthy on all wikis. That is, the current sampling rate is 100%

MobileFrontend (JS):

• Default: 6.25% of all pageviews
• arwiki, bnwiki, frwiki, hewiki, htwiki, jawiki, kowiki, viwiki, zhwiki: 20% of all pageviews
• 100% when the user clicks a suggested edit card on their newcomer homepage
• 100% when $wgMFSchemaEditAttemptStepOversample is either "visualeditor" or "all"

Note well that $wgMFSchemaEditAttemptStepOversample is "visualeditor" by default and "all" on azwiki, bgwiki, zh_yuewiki, cawiki, hrwiki, dawiki, etwiki, fiwiki, elwiki, huwiki, mswiki, mlwiki, nowiki, ptwiki, rowiki, srwiki, svwiki, tawiki, thwiki, and urwiki. That is, the current sampling rate is 100%
