Here's a thought: ring taps...
Ethereal supports ring buffers... it can capture for a while, writing
to a file, and then moving on to use the next file in the ring...
If the file switching could be done at regular time intervals (which
might already exist, I'm just not familiar with the feature), and the
io,stats could be "drawn" and then reset at each transition... Then you
*should* be able to get graphable data at regular time intervals.
To me, it sounds like it should be a straight-forward item to
implement. There is (or should be?) a well defined point in the code
where the transition between ring buffers occurs. Putting in a few tap
specific calls in there should be relatively straight-forward.
Of course, finding the "right" way to do that so that any and all
taps can conditionally benefit from such an feature would be the
hardest part... ie. it might be easy to get it to work, but hard to get
it to work right :)

Hi,
First, thanks Ronnie for pointing out the -z option of tethereal. My
RedHat
comes with tethereal 0.9.6, which seems not to have this option... (wget
and
make are not far away...).

Jason was right, "it's a matter of trying to make what already exists
work in
real time" !
I'll continue thinking about possible solutions. If you have other ideas
(either completely new or based on tethplot), please let me know.
Regards,
Loïc
