Protocol for reporting

Rudder 3.1 uses syslog messages over UDP by default for reporting, but if you upgraded your server from a previous version, you will keep the previous setting which uses syslog messages over TCP.

You should consider switching to UDP (in AdministrationSettingsProtocol), as it will prevent breaking your server in case of networking or load issues, or if you want to manage a lot of nodes. The only drawback is that you can lose reports in these situations. It does not affects the reliability of policy enforcement, but may only temporarily affects reporting on the server. Read perfomance notes about rsyslog for detailed information.
