I believe that the L2 status tools mentioned by Joe are:
- the L2 status MA (based on the RDB MA) and which contains L2 
information. It is based on a SQL database that the NRENs populate with 
the L2 status information they extract and aggregate to fit with the 
JRA4 data model.
- the L2 status MP developed in perl by DFN LRZ within JRA4 (Matthias 
and Mark are Cc-ed). It is based on a XML file that the NRENs populate 
with their L2 status data they extract and aggregate to fit with the 
JRA4 data model.

For more information, please refer to :
http://wiki.geant2.net/bin/view/JRA4/E2EMonSoft and in particular the 
document: http://wiki.geant2.net/bin/view/JRA4/DmsDocE2EMonDeploymentGuide
To access the visualisation: 
http://cnmdev.lrz-muenchen.de/e2e/html/G2_E2E_index.html

Those two perfSONAR (compliant) web-services are used by a visualisation 
tool developped by LZR to display the L2 link status. (currently it 
shows only the last 5 min status).

This raise, amongst other, the following questions:
- what is the support model for the JRA4 SW?
- would it be released within the pS core?

Cheers,
Nicolas
