MRTG will give you a listing of the current and historical data rates through an interface (https://oss.oetiker.ch/mrtg/) Cacti would be another example (but probably way overkill for what I was looking for).

I figured out that netdata can monitor a router via SNMP - you'll need to add a conf file containing the target device and snmp communities to /etc/netdata/node.d/snmp.conf (see https://github.com/netdata/netdata/tree/master/collectors/node.d.plugin/snmp for an example, I pretty much cut and pasted the example below "If you need to define many charts using incremental OIDs, you can use something like this:" just changed the IP and community strings), and then restart the container, you should get a new section on the right side "SNMP switch" with your graphs for each interface on the router.
