Session Volume by Domain

This Metric will display the count of unique sessions with a breakdown by subdomain for all sessions over the last month. Note that a single session can contain activity across multiple subdomains and will count towards each domain where activity occurred. The sum of unique session counts for each domain may be greater than the total number of sessions for that time period. Find more information about how Fullstory treats data capture across domains here.
