What

This little service listens for Syslog packets on network and forwards them to local Systemd journal.

Some configuration is available via command line.

% ./syslog-journal -help

Usage of ./syslog-journal:
    -default-priority int
          Used when priority can't be inferred from message. (default 6)
    -force-priority int
          Overwrite message priority. -1 to pass as is. (default -1)
    -format string
          Fields: ReceiveTime, Timestamp, Addr, Priority, Tag, Content.
          See syntax at https://golang.org/pkg/text/template/
          (default "from={{.Addr}} {{.Tag}}: {{.Content}}")
    -journal-buffer-size int
           (default 32768)
    -listen-udp string
          Empty string to disable. (default ":514")
    -queue-length int
          Store parsed messages in memory before blocking on Journal sending. (default 100)
    -udp-buffer-size int
           (default 16384)

Why

It may be possible to configure rsyslog or syslog-ng to do the same, and I've had success with plain forwarding via rsyslog, but didn't find a way to add source address info. Now with Systemd spread there's no need in full featured syslog server so I think this program is a better replacement for complex configuration.
