* Provide options for various modes, with the default being the old
(KB/t, tps, MB/s) tuple, so the output can remain compact.
I recommend one that does (tps, MBr/s, MBw/s).
Yeah, thought about that, too. Will look into it.
* Maybe we can remove the tty statistics and add aggregate or
primary interface network statistics. Nobody cares about tty
statistics any more but it would be kinda cool to see network
stats there mixed with the disk stats.
Can I get that from devstat also? Well, could just look at systat
-ifstat, right? How to determine the "primary" interface?
If you don't want to see tty (which I fully understand :-) ) you could
just use iostat -dC.
I am considering removing the tps/r, tps/w from systat -vm 1 and
just having tps, but keeping MBs/r and MBs/w. I think people will
get more out of an aggregate tps stat. Then for systat -vm 1
we would have: (KB/t, tps, MBs/r, MBs/w) (I should rename those to
MBr/s and MBw/s I guess too).
Yep, Megabyte-seconds divided by writes (and reads) doesn't make a
horrible lot of sense :-)
