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...

Good pdf, thanks for the pointer! says dmilite-plugins-profiler can do it -
is this software in production yet / anywhere?

But need monitoring backend... is that something gridpp-storage people can
provide?

We do need some storage monitoring like the above. Is it in a proverbial
pipeline somwhere?

Is "it's still working" referring to
http://www2.ph.ed.ac.uk/~wbhimji/SRMMonitoring
??? It doesn't seem to be working anymore or do I just not know how to use
it? (not unlikely!)

(Remark: with the same cert & version of firefox, on my Mac I can get
to that page (but can't seem to get any data out of it), but on SL5 get 403
Forbidden. Can everyone else get to that page?)
