Carl,

The origin_v_upstream was added tp the LDM in 5.2 as part of the product
structure (eg _v_upstream is appended to the origin hostname). It is not 
being added by rtstats. Each LDM will replace the _v_upstream string with the
hostname of the machine that the product was received from.

Prior to LDM5.2, the only way to determine topology was for sites running
mailpqstats from their cron to examine their ldmd.log file for "topo" entries.
Unfortunately, the "topo" line in ldmd.log is only emitted upon the
initial connection, making the topology information very static.
The addition of the upstream information allows the statistics to determine 
what the topology is at any moment, including if there are multiple
paths to a site. Eventuellay, we would like to improve IDD routing
using this information.
