hi Winnie,
So, two rather different questions, with two rather different answers :)
1) Re local storage monitoring (as the GridPP monitoring plugin used to do).
There's a long and complicated story about this one, which goes back at least two iterations of the DPM core development team at CERN. Suffice to say that the original intent of the CERN DPM team was that the dpm nagios plugins (also referenced in Lukasz' original post) would provide the useful storage monitoring interface. It is not clear that they do so.
The dmlite-plugins-profiler is a later development (IIRC) also intended to provide detailed monitoring about the state of a DPM, on the model of the Xrootd monitoring schema. (It's actually also a component of the HTTP Deployment Task Force requirements, or at least feeds into them.)
The output is designed to be parsed by an XrdMon (a specialisation of the GLED system), and I don't see why we couldn't set such a thing up (there's already one at CERN, as documented in Fabrizio's talk.)
(I'm still debugging the storage per spacetoken collection, which seems to be a bit broken in the revision of the code I have). I wasn't planning on publicising it until it worked a bit better, but...
