Install syslog sudo yum install rsyslog

Edit /etc/rsyslog.conf and uncomment the below lines. This is a basic config but will be commented out for a better config.

$ModLoad imudp
$UDPServerRun 514

$ModLoad imtcp
$InputTCPServerRun 514

Current running config is found here and shown below. This runs on udp 514 and automatically formats logs and locations based on the host. Save this config in /etc/rsyslog.d/

module(load="imudp")
input(type="imudp" port="514" ruleset="RemoteDevice")
template(name="DynFile" type="string"
	string="/var/log/remote-syslog/%HOSTNAME%/%$YEAR%.%$MONTH%.%$DAY%.%PROGRAMNAME%.log"
)
ruleset(name="RemoteDevice"){
	action(type="omfile" dynaFile="DynFile")
}

Start syslog with sudo systemctl start rsyslog
