perfSONAR User Q&A and Other Discussion

["Nina Jeliazkova" <>]

Frederic,

Just a wild guess - please ensure that the new row for your service in
perfsonarUI's MA.conf is as follows (note the parameters after the service
URL):

YOURSERVICE,http://193.49.159.135:8080/perfSONAR-RRD-MA-2.0/services/MeasurementArchiveService,http://schemas.perfsonar.net/2.0,"",http://ggf.org/ns/nmwg/characteristic/utilization/2.0,http://ggf.org/ns/nmwg/characteristic/utilization/2.0

Best regards,
Nina
