Platform events can be custom events, which are platform events that you define, or standard events, which are the events that Salesforce defines, including Real-Time Event Monitoring events.
| Event Type | Counts towards event publishing allocation | Counts towards event delivery allocation and entitlement via add-on |
|---|---|---|
| Custom events that you define |  |
|
| Standard events. See Standard Platform Event Object List. |  |
Check the "Event Delivery Allocation Enforced" section in each event reference documentation in Standard Platform Event Object List. |
| Real-Time Event Monitoring events. See Real-Time Event Monitoring Objects. | |

When allocations aren’t enforced, system protection limits apply.
