A while ago I found that I needed power usage stats also (these new P4
Zeons suck up a lot of power :). I got some baytech PDUs with LEDs and
console access (forget which specific model). Looked very cool. Except
that I am in Los Angeles county. LA takes a dim view of selling
equipment that is not UL certified. Apparently it is illegal to both
sell and operate :( After several months of "We should have it soon", I
bought APC units.
The APCs (AP7901) are very nice. snmp and ftpable stats. They even do
ssh!
No individual per ports stats, and only to 1/10th amp. But no more
popped circuit breakers from new servers.

Let's face it, there's no Hollow Earth, no robots, and
no 'mute rays.' And even if there were, waxed paper is
no defense. I tried it. Only tinfoil works.
