New in version 3.9.0.
This module allows Wazuh to forward messages to a Fluentd server. Fluentd it's an open source data collector logger that comes along with great plugins to build your own logging layer. Check it out at https://www.fluentd.org/
This module allows the forwarding of the received messages from a dedicated UDP socket to a Fluentd server. The Fluentd server could be located on the same local machine or a remote machine.
This module works only on Unix systems.
socket_path tag indicates the location of the Unix domain UDP socket to be created by the module. From this socket, the module will read the incoming messages and forward them
to the Fluentd server.
tag tag it's added to every message read from the UDP socket. This allows the user to specify the flow to the Fluentd server internal routing.
An empty tag is not allowed, the module will shutdown if it is not present or empty.
This example is for testing purposes on a Debian machine, with the Wazuh manager installed.
Given the following configuration:
<fluent-forward> <enabled>yes</enabled> <tag>debug.test</tag> <socket_path>/var/run/fluent.sock</socket_path> <address>localhost</address> <port>24224</port> </fluent-forward>
Set up the
socket for logcollector:
<socket> <name>fluent_socket</name> <location>/var/run/fluent.sock</location> <mode>udp</mode> </socket>
Set up a
localfile to read from:
<localfile> <log_format>syslog</log_format> <location>/path/to/your/log</location> <target>fluent_socket</target> </localfile>
On a terminal, run the following commands as root to start a Fluentd server:
apt-get install -y ruby ruby-dev gem install fluentd fluentd -s conf fluentd -c conf/fluent.conf
Restart the Wazuh manager:
systemctl restart wazuh-manager
Write a string to your log file:
echo "message" >> /path/to/your/log
You should see the message on the Fluentd server:
2019-03-28 14:47:40.000000000 +0200 debug.test: "message"
