Segments (also known as profile groups) represent different groups in your customer base. To log segment data for reporting, the /atg/reporting/datacollection/userprofiling/SegmentChangeListenerService listens for ConfigurationEvents. These events occur when updates, deletions, or insertions are made to segments. The listener sends details of segment changes to the /atg/reporting/datacollection/userprofiling/SegmentFileLogger via a data collection queue. The SegmentFileLogger creates the log entry.

The segment_timestamp_unique file contains the following logged information:

The following is an example of the segment log:
