Lightning Logger Event Type

Lightning Logger events contain information from observed Lightning component logs. This event type is available in the EventLogFile object in API version 58.0 and later.

To enable Lightning Logger events, from Setup, in the Quick Find box, enter event, and then select Event Monitoring Settings. Turn on Lightning Logger Events.

The browser sends Lightning Logger event logs to the server in batches. Batches are sent when the user interacts with the page and when the page closes or refreshes. If the user experiences connectivity issues or if their login session expires due to browser inactivity, any pending Lightning Logger event logs on the browser are erased. There isn’t a way to retrieve these lost logs.

Note

For details about event monitoring, see the Trailhead Event Monitoring module or REST API Developer’s Guide.
