I think having the possibility of sending xrootd information to MonALISA
is something we want.
I also agree that we should have a "what we want from this" discussion
independent of the implementations, hopefully with Jacek/Tofigh
participating, too, since they worked on the server side monitoring. Perhaps
we could try to have a short dedicated phone conversation next week? Would
you and Catalin be able to call into the normal xrootd meeting? (19:15
CERN time on Tuesday)
