perfSONAR User Q&A and Other Discussion

["Nina Jeliazkova" <>]

Hi Szymon,

Taking a closer look, I've just found that neither perfsonarUIv0.03 nor
perfsonarUIv0.04 are working with PIONIER.  As you might remember, v0.03 was
introduced in order to support your specific installation.

Actually, there is nothing changed in the SetupDataRequest that is relevant to
your installation (changes in perfsonarUIv0.04/0.05 are relevant to NMVGv2
with xmlns:netutil="http://ggf.org/ns/nmwg/characteristic/utilization/2.0";
namespace). 
Attached are requests that are send by 0.03, 0.04 and 0.05 UI releases - you
can verify these are identical.


Regards,
Nina
