perfSONAR User Q&A and Other Discussion

[Jason Zurawski <>]

Hi Roy;

I apologize, I misunderstood your question.

The use case you are describing is not one that the performance toolkit 
by itself was designed to solve.  Each toolkit instance is meant to be 
'standalone' for the most part - all of the testing and storage 
capabilities in one machine.  They currently don't have a way to 
cooperate by default, and 'push' the data to a designated central 
location.  The underlying perfSONAR-PS software makes ot possible to do 
this, but requires tweaking of some internal files and can't be done 
through the GUI.

If you would like to set up a complete institutional solution with 
multiple test points and a centralized archive there either needs to be 
modifications to each toolkit instance (if this is what you were 
starting with), or you may consider setting up individual services 
through RPMs.  Several campus and regional networks have started doing 
this, but it is a bit more of a 'get your hands dirty' project.

I would be happy to talk about this with you offlist if you are interested.

Thanks;

-jason
