Log event notification listener

Describes the log event notification listener, which lets you know what data was sent to Optimizely Feature Experimentation in a given event batch, and when the batch was sent in Optimizely Feature Experimentation.

The log event notification listener is similar to the track notification listener but provides more granularity. It lets you know what data was sent to Optimizely in a given event batch, and when the batch was sent. For information about event batching, see the corresponding documentation for the Feature Experimentation SDK language. You can use this notification listener to inspect and audit what data you send to Optimizely.
