WUG uses SNMP as well to retrieve bandwidth. Are you trying to create a special view for one of many customers? I'm a little foggy on what you need to accomplish.
Sorry about that, yes in WU we polled the T1 Interfaces on our main router to get the Bandwidth Percent Utilization for each node.
How do I do that in NPM? Is it thru NTA or just added in the Customize Page link of that Node?
NTA will tell you which end devices and apps are using the bandwidth for a particular interface. If you want to know who is suing up the T-1 NTA is the right tool. To get utilization for each interface you have to SNMP poll the interfaces.
