I had both journal and rsyslog working, but I don't know exactly how I 
did it years ago. I have experimented with what those two links propose.

I have, on /etc/systemd/journald.conf:

#ForwardToSyslog=no
#MaxLevelSyslog=debug

On /etc/rsyslog.conf I had:

# provides support for local system logging (e.g. via logger command)
$ModLoad imuxsock.so

I commented that line and added:

$ModLoad imjournal

When I restart the syslog daemon, I get a flush of new entries that it 
reads from the journal. This is not good. And, when I issue:

logger -p local3.info hello

The message gets to the journal but not to the syslog. So I change to

$ModLoad imuxsock.so
$ModLoad imjournal

and now the messages go to both places, but the restart of the daemon 
adds the flurry of entries to the log files again. This is not clean; 
when I do changes to the syslog filtering, I have to restart the daemon 
and everything will be written again.

The weird thing is that with the previous configuration I was getting 
the messages, except some boot messages.

Oh, I forgot to add

$ModLoad mmjsonparse

No difference, though. So I'm going to try the socket method instead.

/etc/systemd/journald.conf:

ForwardToSyslog=yes
MaxLevelSyslog=debug

/etc/rsyslog.conf:

$ModLoad imuxsock.so
#$ModLoad imjournal
#$ModLoad mmjsonparse

I restart both services, I send a message with logger... everything 
seems correct.
