perfSONAR User Q&A and Other Discussion

[Sowmya Balasubramanian <>]

Hi Roderick,

There was a bug in the MA client library which was causing this issue.

The details about the issue can be found here: 
http://code.google.com/p/perfsonar-ps/issues/detail?id=654

The graph uses test-keys to retrieve test data from the MA. So, when you 
change from 1 month to 3months, what is happening is the order of the 
keys that you send in the url also changes. This results in different 
graphs.

This issue has been fixed and the fix will be available in the next 
release of perfSONAR toolkit (perfSONAR-3.3). We are currently in the 
process of doing a 3.3-rc2 release.

Thanks,
Sowmya
