How it works...

The daemon logging to text files is rsyslogd (on some older systems, it might be syslog-ng).

This reliable and extended syslogd program writes messages that it reads from one of two locations, imuxsock (old) and imjournal (new); this comes directly from the syslog(3) syscall man page:

syslog() and vsyslog()syslog() generates a log message, which will be distributed by syslogd(8).

Note that syslogd (referenced here) is an old program, superseded by rsyslogd.

If there's more than one entry of the same name, in the man pages, you can specify the section by using the number. In this case, it would be man 3 syslog on the command line.

rsyslogd configuration resides at /etc/rsyslog.conf and gives us the first bit of information ...
