systemd-netlogd

Forwards messages from the journal to other hosts over the network using the Syslog Protocol (RFC 5424). It can be configured to send messages to both unicast and multicast addresses. systemd-netlogd runs with own user systemd-journal-netlog. Starts sending logs when network is up and stops sending as soon as network is down (uses sd-network).

Configuration

systemd-networkd reads configuration files named /etc/systemd/systemd-netlogd.conf and /etc/systemd/systemd-netlogd.conf.d/*.conf.

[NETWORK] SECTION OPTIONS

   The "[Network]" section only applies for UDP multicast address and Port:

   Address=
       Controls whether log messages received by the systemd daemon shall be forwarded
       to a unicast UDP address or multicast UDP network group in syslog RFC 5424 format.

       The the address string format is similar to socket units. See systemd.socket(1)

   Optional settings

   StructuredData=
       Meta information about the syslog message, which can be used for Cloud Based
       syslog servers, such as Loggly
