The Event Publishers tab uses these fields to provide a list of entities generating and sending events onto the Salesforce Event Bus, so you can see how various components contribute to your event publish entitlements.

- Publish Method: The method used to publish the event, such as Apex, flow, system, Pub/Sub API, REST API, Bulk API, or SOAP API.
- Number of Events Published: The count of events each publisher sent,‌ in a time series or as a total for the last 24 hours.
- Last Publish Time: The timestamp of the method’s most recent event publish in your local time zone.

The Event Subscribers tab uses these fields to offer insights into which clients listen for and consume events from the Event Bus, helping you monitor usage against your event delivery entitlements.

- Subscription Method: The method used to subscribe to events, such as Apex, Pub/Sub API, streaming API, Lightning web component, or Event Relay.
- Number of Clients (Subscriber ID): The number of distinct subscriber clients for this subscription method.
- Number of Events Delivered: The count of events delivered to the subscriber.
- Last Delivery Time: The timestamp of the delivery method's most recent event delivery in your local time zone.
