I’d need some clarification about what you mean.  What’s doing the reporting?

Thanks for the reply Mark. I'm trying to field answers from folks who are asking a lot of "Why" and "How come" questions that I simply don't have the answers for.

Here's some assorted examples. While I use one particular site for the example here, the problems are not isolated to that one but can be seen on many others (from here).

1. The most common one so far...
   I attempt to go to the other end of a test, in this case "psonar3.fnal.gov' and it returns an error message (attached as "perfSONAR Toolkit psonar3.fnal.gov.png") that says:
   Error loading test listing; measurement archive unreachable:
   http://psonar3.fnal.gov/esmond/perfsonar/archive/

N.B. We can even get that message from our system at times.

2. The reason I went to that system to look at traffic back to our site is because when I pull up the graph of the traffic BW measurement, it shows a throughput line
   (attached as "pS_results_between_18.12.1.172_and_131.225.189.73-A.png")
   and it has the IPv4 throughput graph but if you click the display of the "Forward" data off
   (see "pS_results_between_18.12.1.172_and_131.225.189.73-B.png")
   you get NO reverse data. This is not the way it has been working in the past and it seems to "break" (for lack of a better term) the ability to look at the traffic "overlaid" so that abnormalities can be correlated easily and accurately. (And if the data is zero then it should show as a flat line at "0" IMNSHO)
   

Both machines are running the docker version of the pS toolkit.

Thanks for everyone's time.
