Network management software with high detailed traffic report

Well, on the RSP720, the "show interface" byte counters are definitely not
every second, though I can't say it's been as long as 9 seconds.  I
typically look at them while making changes and they definitely stand still
for a few seconds.

That is most certainly NOT true.  The 'show interface' counters update at 
least once a second.  Perhaps you are thinking about the rate counters 
that are often _configured_ to use the last 30 seconds of data to compute 
the average but also update much more often than every 30 seconds (and 
default to a 5 minute average).
