perfSONAR User Q&A and Other Discussion

["Robinson, John-Paul" <>]

Hi,

Thanks for the feedback.  I'm working with perfsonar 5.1.2 so it's the grafana interface.   I navigated to the the pair explorer plot you mentioned.  I see all my hosts I have tests set up in the destination drop-down, but I only see my own hosts in the source.  So I can't swap the tests results around.

Hi,

I'm wondering what steps are necessary to enable the plotting of the forward and reverse thoughput results in the web UI.   This may actually be rooted in an issue of those results not being logged or the tests not being performed. In any case, I'd like to fix the problem.

In ps releases prior to 5.x I was able to just set up tests and select "send and receive" in the test set up UI and the results would show up for both directions of successfully completed tests.  In all my setups since switching to 5x, this has not worked out of the box.

I did a fresh install of 5.1.2 on two test boxes on Ubuntu 22.04 on the same lan segment.  I set up a throughput test on each one pointing at the other node.  I selected the "Send and Recieve" in the advance testing parameters.   When I look at the plots I only see the tests that are outbound from the host.  I never see the reverse (inbound) test results. I can run tests in both directions from the command line using pscheduler.

I'm not sure where to look to debug or fix this issue.  Could you provide some guidance?

Hi John-Paul,

It's not 100% clear to me at what dashboard you're looking at.

Provided you have toolkit installed there is a "perfSONAR Endpoint Pair Explorer" Grafana dashboard. On top of it there are drop-down list selection boxes where you can select Source and Destination hosts. At a time you can select one direction. In order to see opposite direction you need to swap hosts.

regards,
