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.
