 ## 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.
