perfSONAR User Q&A and Other Discussion

[Tadeja Saje <>]

Hello.
We deployed a perfSONAR testpoints.. Two(mp-tpl-pf2.arnes.si) of them with http://software.internet2.edu/rpms/el7/x86_64/main/RPMS/perfSONAR-repo-0.8-1.noarch.rpm and then upgraded http://software.internet2.edu/rpms/el7/x86_64/main/RPMS/perfSONAR-repo-0.9-1.noarch.rpm. This works ok. Two of them we(mp-ijs-pf1.arnes.si) installed with http://software.internet2.edu/rpms/el7/x86_64/main/RPMS/perfSONAR-repo-0.9-1.noarch.rpm. we cannot perform measurements to testpoints installed with http://software.internet2.edu/rpms/el7/x86_64/main/RPMS/perfSONAR-repo-0.9-1.noarch.rpm.
My debugging:

not working testpoint:
