Ran into a ton of issues using Cacti (mainly no one really supports the templates, plugins, etc for F5) so I'm trying a different flavor of monitoring solution called Zabbix which is another open source monitoring solution that has a few articles referencing F5 and a lot of the articles I'm finding are more recent (2017 and newer) where Cacti was pre 2017.
So let's start with some instructions
Install the Zabbix Repository
Download the RPM
Seems like this should be easy, especially since there is a yum install for cacti but oh no, nothing is what it seems. If you follow the below instructions (well as of January 2020) then you have a good chance at being successful. Please note, this is best case and no guarantee it will work but it worked for me. This also will help me keep track of some helpful commands I used for the future.
Open and edit SELinux configuration file.
