In addition to the same output as the scan parameter of sp_help_rep_agent, the scan_verbose parameter displays the number of log pages to be processed by the Adaptive Server RepAgent from the current marker to the end of the log.
See the scan_verbose parameter of sp_help_rep_agent in the Replication Server Reference Manual.
