I'm looking to monitor traffic (incoming, outgoing and total monthly) on a few ports (mostly TCP) and I've done a ton of Googling around and everything leads to software I either can't manage to use, or I can manage to collect and graph data at the port level.
I currently have Zabbix installed and I can monitor traffic on an interface, but I haven't quite figured out how to on the port level.
I also have Ntop installed though I can't access the web gui just yet.
My main question is: Is the an 'almost out of the box' application that I can use to monitor traffic or has anyone had some luck with Zabbix and port level monitoring (or an integration of Ntop).
Note: Please don't mention Cacti.
