perfSONAR User Q&A and Other Discussion

[Humberto Galiza <>]

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.
