(Again.)

The pieces are:

 * A monitoring daemon (clientside/protogeni/shared-node-monitor), which
   runs in each Xen shared node dom0, and gathers node and interface
   statistics.  It communicates these over the event system with...

 * A listening daemon (event/monitoring/shared-node-listener), running
   on the local boss node, and inserts everything it hears into the
   MySQL database "monitoring".  This database is also used by...

 * A site-wide monitoring daemon (protogeni/scripts/mondbd), periodically
   polling the normal testbed database (nodes and interfaces tables) and
   copying snapshots of the important pieces into the monitoring database.

 * The monitoring database is also read by a WWW front end invoked as a
   WSGI process by Apache.  This front end is developed by the GPO and
   modified to work with ProtoGENI, and is maintained in an independent
   repository.
