RRD Summary does not report data on 3100
RRD Summary package version 2.0_1 does not report any data on 3100. Upon installing the package, 0 GB is reported on any interface. I tested on amd64 and it works as expected, so this has only been seen on 3100. It has been seen on multiple 3100s.

There are some users on the forum who report that it will begin counting after some time passes, https://forum.netgate.com/topic/161077/solved-rrd-summary-no-data. We have seen a report of a user waiting 3 months and still not seeing data counted there. In my case, I passed quite a bit of traffic and did not see that change.
