contains many useful packages, which are not included in RHEL. A few dependencies of syslog-ng are available this repo. You can enable it by downloading and installing an RPM package:</p>

3. Add the repo containing the latest unofficial build of syslog-ng. By the time of writing it is syslog-ng 3.24 and it is available on the Copr build service. Download the repo file to /etc/yum.repos.d/, so you can install and enable syslog-ng:</p>

4. It is not strictly required, but you can avoid some confusion, if you also delete rsyslog at the same time:</p>

<div class="" style="word-wrap:break-word; line-break:after-white-space">RHEL and derivatives uses rsyslog by default, so if you plan to use syslog-ng instead, you should remove rsyslog first. Other configs are highly depends on your usecase (like adjust kernel
parameters for heavy UDP traffic and so on). Also quite generic people are facing with issues with selinux and firewalld but obviously there are solutions for any of these (other than turning off these services :))
