perfSONAR User Q&A and Other Discussion

["Lixin Liu" <>]

Hi Andy,

Thank you very much. Yes you are correct that sites-CANARIE.json
was out of date (I am actually using ps-mesh/sites-CANARIE.json
in production servers). After I fixed it, the meshconfig loads
correctly.

I am still confused about the change of read_url format. The page
http://ndt-sfu.westgrid.ca/esmond/perfsonar/archive/?format=json
gives me a very long line and there is no "read_url" in the line.
All my json files are converted from .conf files using build_json
command. So what kind of changes I need to do for .conf files?

Thanks again!

Lixin.
