 ## How the daily cap works
 Each workspace has a daily cap that defines its own data volume limit.  When the daily cap is reached, a warning banner appears across the top of the page for the selected Log Analytics workspace in the Azure portal, and an operation event is sent to the *Operation* table under the **LogManagement** category. You can optionally create an alert rule to send an alert when this event is created.
 
+The data size used for the daily cap is the size after customer-defined data transformations. (Learn more about data [transformations in Data Collection Rules](../essentials/data-collection-transformations.md).)  
+
 Data collection resumes at the reset time which is a different hour of the day for each workspace.  This reset hour can't be configured. You can optionally create an alert rule to send an alert when this event is created.
