Well, take your pick.  The code has both.  The interface stuff was 
easier then I thought.

Trying that out now or better trying to remember :)

Glad you hit me cuz I was working on the disk (wait|run) queue resident 
and service time stuff - or I should really say looking at it - and I 
need to get the network stuff submitted.

For me, I would like to know what the wait and run queue statistics are. 
  Currently, these stats are computed but not collected in the text 
files.  I don't like how it only shows service time, appears to ignore 
resident time, and doesn't collect/compute response time - or maybe it 
does, I need to look at the code some more.

This of course brings up the recent RAW disk code topic which is the 
code I've been modifying.

That's right - no bytes sent or received - unless its somewhere I didn't 
notice.

Got the network code - remind me how you like the log file entries again.
