Export of SSL Session Logs from the SSL Visibility appliance results in no ssl_session_log.*.bin files being exported. For example, the exported .tgz file might contain only the following files:
SSL Visibility sets a size limit of 32MB for a session log file and total disk usage of 8GB for all the session logs.
It is possible that the first session log is added to the export list, but is deleted due to disk usage limitations before actually being added to the .tgz archive. In that case, no session log file will be exported.
