Nina,

Thank you for your help. I finally found the descrepancy.
I fact this was linked to the LD_LIBRARY_PATH env variable set during 
RRD-MA 2.0 installation phase.

At that time everything worked well. (I could retrieve the interface 
graph by clicking the "Retrieve all" button.)
However, once rebooted the LD_LIBRARY_PATH is unset and that's the 
reason why RRD graphs are not displayed in PerfSONARUI.

I tried to consult the log in:
/home/perfsonar/perfsonar-bundle-2.0-RC1/webapps/perfSONAR-RRD-MA-2.0/WEB-INF/logs/perfsonar_debug.log

But could not find explanation or clue showing that the LD_LIBRARY_PATH 
was not set.

Anyway, I set LD_LIBRARY_PATH to 
:/usr/lib/:/home/perfsonar/perfsonar-bundle-2.0-RC1/perfSONAR-RRD-MA-2.0/perfsonar/contrib/rrdjtool/build/
And this solved the problem.

I suggest to put this in the RRD-MA installation FAQ.

Thanks to all again for your help and effort
Bgrds/Frederic
