perfsonar development work

["Nina Jeliazkova" <>]

Hello all,

Trying to use lookup service in PerfsonarUI, here is what is not clear to me:

1) Is it mandatory for a service to register information other than pure
information about service (URL, name), e.g. interfaces?

2)Is there any way to discover schema supported by the service (for
PerfsonarUI to provide backward compatibility, like current MA.conf settings).
 I understood supported event type can be figured out from interfaces
registration, but what about services that don't register these? Additionally,
is it possible for interfaces within same service to support different event
types?

3)Is there a way to distinguish between different types of MA services (e.g.
utilization MA service and Hades service). I saw a suggestion to have subType
parameter, but not sure it is implemented already or if it will be mandatory.

4)For PerfsonarUI what will be the best approach - contact single
preconfigured LS, or have a list of LS to send queries? 


I am aware these points have already been discussed, but not sure there is a
definite answer or it could be it is already explained in some documentation
I've missed.


Best regards,
Nina
