syslog-handler doesn't work

[dafi]

I added to my standalone.xml the syslog-handler configured inside a logging-profile but no log messages is visible inside the file /var/log/messages

The logging-profile has other handled configured (console and file) and these works fine

Obvioulsy the syslog is added inside the root-logger/handlers

I don't understand what I'm missing, may you help me?

Below the full definition of my logging-profile relative to wildfly-26.0.1.Final

The app inside the MANIFEST.MF contains the line

Logging-Profile: dafi-app-profile

Are you seeing logs in the dafi.log?

[dafi]

The dafi.log file contains the application log printed from my own code but nothing related to errors relative to syslog so it's impossible to understand if some problem occurs from syslog handler

[James Perkins]

Is your syslogd listening on port 514 with UDP? Or maybe it expects a different format. The default is RFC5424 and maybe it expects the older RFC3164 format. These are just some thoughts.

[dafi]

My admin told be the server is listening to UDP/514 but running the command "sudo netstat -pnltu" I discovered this is false

Finally him configured the server and now everything works fine

without your suggestion I never would have thought to check the server config, thanks!
