Gelf input gives empty log file

[huybanh]

Hi all,

I have the following config in my /etc/td-agent/td-agent.conf:

<source>
@type gelf
tag abc
port 12201
bind 0.0.0.0
</source>

<match abc>
@type file
path /var/log/td-agent/events
</match>

The application is Quarkus based, with application.properties:

quarkus.log.handler.gelf.enabled=true
quarkus.log.handler.gelf.host=localhost
quarkus.log.handler.gelf.port=12201

Using tcpdump I saw the application sends data on port 12201. However, /var/log/td-agent/events/buffer.b603feefc2c5dc8c96875a74d8039ce56.log is always empty.

Can someone tell me what is missing/wrong?

Thanks in advance,
