<a name="tracking-usage-logging"></a>

To help you to track your Detective activity, the **Usage** page shows the amount of data ingested and the projected cost.
+ For administrator accounts, the **Usage** page shows the data volume and projected cost across the entire behavior graph.
+ For member accounts, the **Usage** page shows the data volume and projected cost for their account across the behavior graphs that they contribute to.

Detective also supports AWS CloudTrail logging.
