Metrics

client_level_daily_active_users_v1

Firefox Desktop Client-Level DAU

This metric reports DAU values similar (but not necessarily identical) to the official DAU reporting definition. It's generally preferable to use the official DAU reporting definition when possible; this metric exists only for cases where reporting client_id is required (e.g. for experiments). 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.

For more information, refer to the DAU description in Confluence. For questions please contact bochocki@mozilla.com or firefox-kpi@mozilla.com.
