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.)
Fabrizio reported on their dashboard here:
https://indico.cern.ch/event/324705/contribution/13 but has always had his
aim to be a Worldwide DPM/Storage Monitor.
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.)

2) Wahid's old Storage Monitoring at that URL (
http://www2.ph.ed.ac.uk/~wbhimji/SRMMonitoring ) was indeed what I was
referring to, and at the time of writing, it was working(!). Since then,
Wahid's webspace was precipitously removed at Edinburgh, but a replacement
(and mostly working, although I'm still prodding it) is at
http://svr028.gla.scotgrid.ac.uk/monitoring
(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...
