perfSONAR User Q&A and Other Discussion

[Takatoshi Ikeda <>]

Dear Jason, Piotr and Fausto,

Thank you for your help.

By changing new RRD MA url of GEANT, I could get the data.
My application client also does not support the url redirection.

I got this url in perfSONARUI, not LS.
So, I'd like Piotr to chenge the URL in perfSONARUI, if possible.
