1) Yes, you need to configure DCIs with relevant OIDs. This typically is done in a template, for modular things like PSUs instance discovery can be used to autodetect things. Feel free to ask for more details.
2) Since v 5.something we have out-of-the-box templates for traffic monitoring, see under Templates->Interface traffic. They are not applied by default (to avoid surprise on large installations with thousands of network devices), so you need to add custom attribute "Template.InterfaceTraffic" with value "YES", you can just do it on Infrastructure Services and put "Inheritable" checkbox.
