Data scanning occurs when a Sumo Logic query is executed across log data (e.g. Log Search, Dashboards, Monitors). A data scan facilitates the query and retrieval process of a log search by traversing table items from beginning to end and assessing each item against specified values derived from the query. Scan volume is the total storage volume that is scanned on the platform. Data scanning offers a more efficient way to search for and access data and it can be used to quickly locate, access, and analyze data stored.
