perfsonar development work

["Vedrin Jeliazkov" <>]

Hi again,

After some further tests we noticed that replacing "utilization" with
"http://ggf.org/ns/nmwg/characteristic/utilization/2.0"; (either in MA.conf
(twice!) or in the Playground tab) helps, but doesn't solve all issues. In
this case perfsonarUI retrieves successfully hostName, ifAddress, ifName,
ifDescription and Capacity, but fails to retrieve utilization data. The
service returns the following error to the respective SetupDataRequest:

- - - - 8< - - - - 

No output metadata was returned by MessageHandler. Maybe there was no data
trigger, or data trigger  didn't have valid metadataIdRef?

- - - - 8< - - - -

Please see attached query and response.

Best regards,
Vedrin
