outline of monitoring issues for review

["Mark M. Ito" <marki@jlab.org>]

Folks,

To get the ball rolling, I wrote down a list of high-level monitoring 
issues that could be discussed-before/written-for/presented-at the 
upcoming systems review. I'm trying to gauge what the right level of 
abstraction should be. It is on the wiki at 
http://www.jlab.org/Hall-D/software/wiki/index.php/Monitoring:_Outline_of_Tasks_and_Issues
 and attached to this message as text. The next steps include filling 
out some detail on what actual quantities need to be monitored. See 
Eric's email for some contributions to the list.

Comments, please.

Sorry for the multiple list thing; didn't know where to send this. 
Suggestions on this welcome as well.
