Ah, got it.  I have been using Weathermap with Cacti for this purpose,
I am hoping to be able to use the version of weathermap that isn't
integrated with Cacti (weathermap4RRD) with PNP interface trending
graphs so I don't have to maintain an instance of Cacti just to get
core network bandwidth utilization.

Another way to go for saturation / utilization is Netflow from a core
router and then use something like NfSen, which I also use at work.

If you have a really big budget :) OpNet produces a very nice suite of
tools for network performance analysis, both online and offline.

Weathermap will let you display point to point latencies.
