Gmond is reads information from gmetad which reads from the tcp udp, so I imagine you need to worry about the web side of it- openning the udp at least. I am trying something like this, using my phone right now:
ipfw add state udp 0.0.0.0:8649 But Nagios will be part of serving a web page though. If you don't want that, don't worry about it. systemctc status gmond gives you red? BSD automatically enables gmond and gmetad on startup. You should have a hidden file to handle this. You must match the BSD file structure. Why Ubuntu will run what Centos will not, I can't say. SourceForge docs are written for debian.
