perfSONAR User Q&A and Other Discussion

[Pol Llovet <>]

Just to chime in, these are precisely the same things we are using PS for.  With one addition: given the requirement by NSF to have perfsonar numbers to back things up, we have a portable perfsonar node to do ad-hoc testing to evaluate point-in-time health of a network endpoint. 

Robert: My experiences is that if you go over ~20 testing endpoints, the PS gui gets very slow.  Maybe that's been corrected?

Hey Robert;

Thanks for offering this clarification - the short answer is ‘no’, there isn’t a succinct location that describes these sorts of use cases.  The longer answer is:

        1) it is needed

        2) the project can address these (and others)

        3) in the meantime - there are oodles of (admittedly) scattered things that address these use cases on the training page:

        http://www.perfsonar.net/about/training-materials/

In particular you may want to look at the “Deployment and Regular Testing” materials on this page:

        http://www.perfsonar.net/about/training-materials/201503-ps-training/

It may help you with some of the items below, and if you have additional questions we can drill down more.

I will alert you, and the list, when we are able to address #2 from my list above.

Thanks;

-jason
