Monitor Event Usage Against Your Allocations
Check your event publishing and delivery usage and maximum allocation in Setup, or using REST API or Apex.
Check your event publishing and delivery usage in the user interface. From Setup, in the Quick Find box, enter Platform Events, and then select Platform Events. The usage is shown in the Event Allocations section.

If your org purchased the add-on for platform events or change data capture, the grace allocation is displayed in addition to the allocation for daily event delivery. The daily event delivery usage corresponds to the DailyDeliveredPlatformEvents REST API limits value. The monthly event delivery usage is also displayed. It corresponds to the MonthlyPlatformEvents REST API limits value. To view the usage-based entitlement in Setup, check the Usage-based Entitlements related list in the Company Information page.
