Zabbix agent on freenas

I finally get to zabbix and so far love it.
i am in the process of installing it on freenas using : https://zabbix.org/wiki/Install_on_FreeNAS
this page have been last update on jan 2018, so wonder if there is a better / updated way
or is it still fairly accurate… of course with some update…
the template as well seems pretty old :frowning:

I just load the Zabbix Agent on our FreeNAS systems
