Hi Richard,

"sh circuit counters <subs ID> queue" will get you started:

Redback#sh circuit counters L2TP LNS 2064 queue
Circuit: L2TP LNS 2064, Internal id: 5/2/2064, Queue Policy: link-4q

of course that just gets you total sent bytes, but at least you can  
check if WRED is dropping anything or if you're filling any queues.

The most information comes from "show card X circuit handle <handle>  
detail", where X is the card number where the circuit you're  
interested in is bound, and the handle is the full circuit handle  
from "show subscribers active session <subs ID>".  Haven't really dug  
around to see if any published MIBs support this stuff yet, but my  
guess would be that it probably isn't too difficult for the "circuit  
counters" command, but that the blob of info you get in the "card"  
commands is pretty much internal.

Hope that helps...
