      It looks like the transmit and receive rates are swapped in the bandwidth graph:

      0_1468405903001_Screenshot from 2016-07-13 12:29:45.png

      All of that bandwidth is due to FOGImageReplicator copying my images from lab2-server to Gleeble, but the graph (as far as I can see) shows that Gleeble is the one transmitting lots of data.

      Fog version ??? (SVN 5892) is running on Ubuntu 14.04 on lab2-server, which is also the master node.

        The values should not be flipped any more. I mean worse things have happened, and I suppose it’s possible Gleeble (eth0) and lab2-server (eth0) are on the same setup.

          Hi Tom, what do you mean by “on the same setup”? These are two physically distinct boxes in two different rooms.

            @dolf I was only guessing.

            If they had been on the same setup, it likely would’ve looked a lot stranger (like both nodes would’ve had equal bandwidth usage (slightly delayed because they have to check in two different urls).

              Please update, at the least the version will be fixed.

                When I scp from lab2-server to Gleeble, it still shows an orange line instead of a blue one. When I copy something from gleeble to another PC, it shows that lab2-server is transmitting (the blue spike):

                Maybe toe transmit/receive is not swapped, but rather the server names?

                      I’m hoping a newer commit has addressed this. I’m not “overly” concerned with the graph as all it does is give you an overview. Basically, yes I want to fix, no I don’t know why it’s coming back reversed considering the “failsafe’s” are already in place and should be operational. I hope by using ksort rather than asort that this would now be fixed.

                        Yep, it works now.

                        Just for fun: This is the command I use to pull random data from a remote host (and monitor the speed):

                        $ ssh user@remote "cat /dev/urandom" | pv > /dev/null

                          @dolf That is a pretty sweet command. However, have you heard of iPerf? Or even Flent?

                            Nope. I’ll check it out. But piping stuff around in linux is simple and effective.

                              @dolf Simple doesn’t get the job done when you’re trying to measure bufferbloat, or other multi-variable problems 😉

                              Check out Flent: https://flent.org/
