I am still new to the wonderful world of RouterOS so bare with me please 
I have my RouterBoard 751 running in my small office with a dozen or so machines getting IPs from the built in DHCP server. I have Cacti monitoring the network traffic and graphing everything for me, which is working great.
Is it possible to to monitor the traffic that is being used by each IP handed out by DHCP rather than each ethernet port? I have a few of machines connected through a switch leading to one port on the Mikrotik so my graphs show high usage for that specific ethernet port. Doesnt help when i have 5 potential candidates to be whipped.
I have been searching around for the last week but i cant seem to find any templates for Cacti that would do this; is it possible?
Thanks in advance!
