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). It reads from journal and forwards to network one by one. It does not use any extra disk space.

Installing from source

Install build dependencies:

# On Debian/Ubuntu sudo apt install build-essential gperf libcap-dev libsystemd-dev pkg-config meson python3-sphinx # On CentOS/RHEL/Fedora sudo dnf group install 'Development Tools' sudo dnf install gperf libcap-devel pkg-config systemd-devel meson python3-sphinx

Build and install:

make sudo make install sudo useradd -r -d / -s /usr/sbin/nologin -g systemd-journal systemd-journal-netlog 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 EXAMPLE

Example 1. /etc/systemd/systemd-netlogd.conf

[Network] Address=239.0.0.1:6000

Example 2. /etc/systemd/systemd-netlogd.conf

[Network] Address=192.168.8.101:514

Example 3. /etc/systemd/systemd-netlogd.conf

[Network] Address=192.168.8.101:514 StructuredData=[1ab456b6-90bb-6578-abcd-5b734584aaaa@41058]
