Subject: RRD-MA 2.0 issue
Date: Tue, 17 Apr 2007 16:59:38 +0200
Organization: GIP RENATER

Hello,

I'm still trying to set up RRD-MA 2.0.
During the installation process everything went fine and the test using rrd-database_TEST.xml file is working well.

In order to test the RRD-MA 2.0 with our own data, I used the wrote the confPerfSonar.xml file. (Here attached to this mail)
Then I used http://193.49.159.5:8080/exist/admin/admin.xql?panel=browse&collection=/db/rrdmaconfig to upload the new xml file
describing the RRD repository.

Last week, thanks to Nina Jeliiazkova, I managed to get the graph displayed (Last monday) using PerfSONARUI 0.10 (web start version),
but now I no the graph is displayed ...

During the installation process I used the document Metadata_Configuration_Specification.doc
and also the "stitching part" of the RRD-MA 2.0 installation dicument on the wiki ...

Here attached this mail the xml metadata file and a screenshot of PerfSONARUI0.10 showing that no graph is displayed for the interface.

So my question is:
1- Do, I miss something in the installation/configuration/process ?
2- Is there a "known case" describing this issue ? (Maybe this is part of a FAQ...)
3- What log file to look at so as to solve the problem ? (Here attached perfsonar_debug.log when I click on the interface)

Thanks to all in advance for your help
Best regards/Frederic
