Can you break up the statistics by "PR", "SP", "PRskims" and "SPskims"?
(I suspect that they should have different distributions...)

For the detailed discussions BaBar specific stuff (which most of it will be
initially). Occasional summaries of how the system works and the information
it provides might be interesting for the others here, though.

But not so easily at all sites, which is what I want. It is much easier
for people to cough up their log files than to setup the full monitoring
system with collector and relational database (and then synch that). We'll
try that just at SLAC as it will provide more information than we need for
the immediate use case. (In fact we can 2/3 of the way there just collecting
the redirector log files with the "odc.trace redirect" turned on.)

Ok, I'd like to discuss the admin interface with you, Andy and Fabrizio,
though. When are you back from FNAL?
