how to Add graph for newly created vlan on existing router ?

[kmh8arin]

Cacti has been running and graphing items of interest on our routers.
Unfortunately, a new vlan has been created and I am new to manipulating cacti.
The question: How do I get the newly created vlan added to the interface list for
this host on the New Graphs page?

I have read the Cacti Manual and the FAQ. If the answer is there I did not understand it.

rtfm is valid if it includes pointers to the manual

When editing the device, click on the little green circle next to the data query for interfaces.

Then click "create graphs for this host" at the top.
