At the point 8:42, I think you missed one step, which is add the line into the nagios.cfg file. cheers!

Thanks for the Tutorial. I have a question regarding the current Version 4.0.2. The Xinetd Configuration doesnt show up under the Directory "Sample Config". Also searched the Xinetd directory and so on.. Yet nothing to find but online results. Whats the Procedure from here though? (Working on Cent OS8)
