The daily trace summary report is created when you select Log transactions to daily trace summary file in the Daily Trace Summary box on Settings > oik trace options or Settings > oik action options.
Once selected, the output for each WordPress transaction is logged to a summary file written to the Trace files directory at the end of WordPress’es shutdown processing.
This file is written for each transaction regardless of the trace options.
The status report produced at shutdown is also sent as HTML comments and returned to the browser, when possible.
The summary file contains a record for each transaction, be it a page visit, an admin page request, AJAX or REST request.
A single record is written in CSV format to the summary report.
