Hi,

Looks like you just have UDP tests going and I had you try a TCP test. Maybe try "bwctl -s 10.10.14.2 -c 10.10.12.2 -T iperf3  -v -u -P 1 -t 20 -b 150000000 -i 1”.

Thanks,

Andy

Hi,

Hmm can you run ps auxw | grep 10.10.12.2 and send thr results? I am curious what the BWCTL commands your regular test is running look like. It’s quite possible there is another option triggering the error.

Thanks,

Andy

Hi Andrew,

Thanks for replying. I've run the command you suggested, and I've got:

Hi,

Both the graphs on the MaDDash instance and your local instance look the same and both have red dots:

http://190.103.186.5/maddash-webui/details.cgi?uri=/maddash/grids/ONOS+AmLight+Testbed+-+UDP+BWCTL+Test+Between+ONOS+Bandwidth+Hosts/10.10.14.2/10.10.12.2/Throughput

https://190.103.184.147/serviceTest/graphWidget.cgi?source=10.10.14.2&dest=10.10.12.2&url="http%3A%2F%2Flocalhost%2Fesmond%2Fperfsonar%2Farchive%2F

Looks like around last Thursday (Aug 6th) iperf3 started reporting some malformed results in one direction. You might try running “bwctl -T iperf3 -t 20 -i 1 -s 10.10.14.2 -c 10.10.12.2” and see what you get. 

Hope that helps,

Andy

Greetings,

I'm experiencing problems to visualize the measurements on an experimental pS and Maddash deployment.

I see some red circles at some points of the graph timeline, and when I click on it I got the following error:

"Error from bwctl/iperf3: Problem parsing output: malformed number (no digits after initial minus), at character offset 8661 (before "nan\t\t\t\t}\t\t\t}]...") at /opt/perfsonar_ps/regular_testing/bin/../lib/perfSONAR_PS/RegularTesting/Parsers/Iperf3.pm line 54."

The graph can be accessed via:
http://190.103.186.5/maddash-webui/details.cgi?uri=/maddash/grids/ONOS+AmLight+Testbed+-+UDP+BWCTL+Test+Between+ONOS+Bandwidth+Hosts/10.10.14.2/10.10.12.2/Throughput

I think that it's not a measurement problem because I can see the BWCTL test graph directly on the source host (https://190.103.184.147/serviceTest/psGraph.cgi). However, as I mentioned before, I'm stuck with this error when I try to visualize the results on Maddash.

Does anybody can throw some light on what is causing these errors and what can I do to solve it?

Thanks in advance.
