Metrics

days_of_use

Days of use

The number of days in the interval that each client sent a main ping.

Analysis Periods: daily

Data Source: clients_daily

Statistics: mean

Definition:
COUNT(submission_date)

uri_count

URIs visited

Counts the total number of URIs visited. Includes within-page navigation events (e.g. to anchors).

Analysis Periods: daily

Analysis Periods: daily

Data Source: clients_daily

Statistics: mean

Definition:
COALESCE(SUM(active_hours_sum), 0)

retained

Retained

Records whether a client submitted any pings (i.e. used Firefox).

Data Source: clients_daily

Statistics: mean

Definition:
IF(COALESCE(SUM(pings_aggregated_by_this_row), 0) > 0, 1, 0)

qualified_cumulative_days_of_use

QCDOU

The number of days in the interval that each client sent a main ping, given that the client had >0 active hours and >0 URIs loaded.

Analysis Periods: daily

Metrics

client_level_daily_active_users_v2

Firefox Desktop Client-Level DAU

Client-level DAU. The logic is detailed on the Confluence DAU page and is automatically cross-checked, actively monitored, and change controlled. This metric needs to be aggregated by submission_date. If it is not aggregated by submission_date, it is similar to a "days of use" metric, and not DAU.

Analysis Periods: preenrollment_days28 , preenrollment_weekly , daily , overall , weekly

Data Source: firefox_desktop_active_users_view
