The example use of logger --journald in the man page has a couple of flaws: - It's missing a "MESSAGE=" field. This is supposed to be the primary human readable text. Without it the log entry is invisible in a plain "journalctl" output. - The MESSAGE_ID is supposed to be a 128-bit hexadecimal string that globally uniquely identifies the message type. One can generate such an id with "journalctl --new-id". This patches fixes the above and also changes the example to use a here-document instead of printf. In my opinion it makes the expected multi-line data format more obvious.
