There have been suggestions of good SNMP monitorable power strips here
before, however I'm looking for a power strip with individually
monitorable outlet current (via SNMP).
I've searched google for quite a while and can't seem to separate out such
a beast from all the remote power management strips that just monitor
aggregate usage.
I have an application where I need to record the variation in power
consumption for individual devices over time. I need to monitor about 30
devices in 4 cabinets (8 devices per cabinet or so) in and have a budget
of $4000. I'd like to be able to see current in milliamps or 10 milliamp
increments. I'm looking for an off the shelf device.
If anybody can help me I'd certainly appreciate it.

At the now defunct redundant.com we used baytech strips with the ds-3 (not the circuit) modules to snmp enable the strips. We were able to control each port, and monitor load on each port.
I think we used the RPC22s and the DS-3 console server combo. It was a few years ago so my memory of what we did is a bit fuzzy. Regarding how accurate the modules are, the baytech gear would only be accurate to the tenths if my memory serves me, but they may have improved that since mid '03.

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.
don't know the 7901, but i can sure vouch for the 7900 which joel
recommended to me. it has saved me from using remote hands to
whack a wedged server sooooo many times.

The 7900 is 15A while the 7901 is 20A. They are both part of a family of Rack PDUs.

I had moderate success with this suggestion. Their technical support said
the only product they had that does this is the 4 outlet RPC5 or RPC6
(ethernet version vs serial version). Unfortunately, it costs $644 each
(lowest price I've found so far) and accomplishes it's individual
monitoring by replicating power in and power out plus an ethernet port 4
times. Still, if it's the only one out there I guess they win (although
at $150 per outlet, ouch, that goes over my $4000 budget for this).

We were using RPC14s and the RPC22s. Both worked well. The RPC14s were a bit odd to setup though. For me, It would make a bit more sense to use the RPC14s and connect them up to the serial access server (DS series modules) and then do snmp connections to the serial connections to the power strip. It works well, but is awful slow. The price does seem a bit high from when I actully shopped around for baytech gear a little over a year ago.
