real-time queue stats every 5 sec

[Jay Aikat]

Hi,
	I am looking for an option, if there is one, with pfctl logging queue stats in 
real time.

My pf.conf file has the following:
altq on $ext_if1 priq bandwidth 622Mb qlimit 65535 queue { tcp_q1 }
queue tcp_q1 on $ext_if1 qlimit 65535 priq (default)

I can see updated queue stats every 5 seconds with
pfctl -s queue -v -v

But is there an existing option to change this update to say a different delta 
of time?  I need updates every sec if not every millisecond.

I have looked at pflogd output, but I don't see a way to distinguish which 
packets are queued and which ones are just passed on.  Thanks in advance for 
your help.
--Jay.
