Hello Loukik,

It seems that (finally) PerfSONAR RRD-MA 2.0 is installed
and using PerfSONARUI 0.10 I validated the installation using the TEST 
file in PerfSONAR 2.0 bundle.
So let's say assume that it is a clean installation.

Now I would like to export our own RRD data through RRD-MA 2.0. To that 
purpose:
- I just want to use the existing RRD METADATA file. (the one used with 
PerfSONAR 1.0)
- The rrd file are imported through nfs.

However, as a "newbie" I got few questions (knowing that I followed the 
PerfSONAR 2.0 installation page)
1- The "RRD MA Stitching" section seems to be incomplete: (For RRD MA 
Stitching, refer to:) Now the question is where to go from now ?
2- The "rrd-database_TEST.xml" has validated the installation but at 
this stage how to use our own RRD-METADATA file ?
    I understood that there is the service.properties file to update... 
but is there a document indicating the exact steps when we want to 
publish the information ?
    (I.e: update service.ma.conf_file in service.properties / relaunch 
the install script / re-populate exist database / stop-start tomcat and 
so on ...)
3- In PerfSONAR 2.0 RRD-MAversion, do we have to update the format of 
the existing RRD METADATA file ?
    (Note that this file is working well with PYTHON RRD-MA ). If yes, 
that would explain why the current file is not working with RRD-MA 2.0...
4- I managed to find documentation for RRD-MA in PerfSONAR wiki but it 
was difficult to know if it is outdated information
   (i.e info related to older version of RRD MA, info not relevant) 
Maybe It could be great to have documentation for RRD-MA tied to 2.0 
bundle ?

This was just my "2 cents" feedback as a newcomer.
Anyway, thanks in advance for your help.

Hope to hear from you soon
Best regards/Frederic
