Rsyslog is an open-source software utility used on UNIX and Unix-like computer systems for forwarding log messages in an IPnetwork. It implements the basic syslog protocol, extends it with content-based filtering, rich filtering capabilities, queued operations to handle offline outputs,[2] support for different module outputs,[3] flexible configuration options and adds features such as using TCP for transport.

Configuration:

pico /etc/rsyslog.conf
