CDN-in-a-Box not recording stats

I'm submitting a ...

• bug report

Traffic Control components affected ...

• CDN in a Box

Current behavior:

No matter how many requests are made through cache servers for Delivery Service content, the "Current Bandwidth" of all cache servers is reported as 0, and the transactions per second and bandwidth reported for the Delivery Service in question are always 0.

Expected behavior:

TPS/bandwidth measurements actually reflect traffic on the network

Minimal reproduction of the problem with instructions:

start CDN-in-a-Box, docker exec into some container (I used trafficportal, but almost any of them should work), and run while true; do curl -skvL https://video.demo1.mycdn.ciab.test/; done;, then wait a few minutes and request Delivery Service stats. Alternatively, the charts in the CIaB instance's Traffic Portal will show the same thing: no stats.

Anything else:

It's unclear if the issue is with Traffic Stats or Traffic Monitor, but those two are my suspect list thus far.

At the CDN level, connections show data but bandwidth is always 0 (on the TP dashboard)
