Yes, it appears that the ns library routine "init-monitor" installs
a queue-monitor on a link and adds the bytes/pkts integrator object
your are looking for; this isn't built-in for flow monitor
installation.  So, for now, try this, assuming "fmon" is your
flow-monitor:

	$fmon set-bytes-integrator [new Integrator]
	$fmon set-pkts-integrator [new Integrator]

The only reservation I have about this is that it won't set
the instvars "bytesInt_" and "pktsInt_" in the SimpleLink object...
but I have a feeling it might work for you nonetheless.  Give it a try
and see what happens :)
