LARTC - Aug 2007 - tc class show - leaf?

Is there a way of pulling individual leaf nodes out of the tc -s  
class show dev <thx> command?  Say, similar to:


tc -s class show dev eth0 parent 1:1


except for an individual leaf:


tc -s class show dev eth0 leaf 1:12


Or, better year, is there a way to log or store statistics, so that  
you can pull up such things as max rate, max pps, max backlog, etc. -  
not just the instantaneous output from the above?
