Hello. My question is about flag

--logger_syslog_facility
Set the syslog facility (number) 0-23 for the results log. When using the syslog logger plugin the default facility is 19 at the LOG_INFO level, which does not log to /var/log/system.

I can not find any info why facility local3 (19) with info severity does not log to /var/log/system. I need to forward result log to remote syslog server. How can I do it?
