Dave, I believe Applied Innovations makes a product like you are looking for. Their AIspy should do the trick, and works with all standard transducers, although a source for those escapes me at this moment. I was very impressed with this product. http://www.aiinet.com/ Mike Ventimiglia ----- Original Message ----- From: David Hares <dhares@networktwo.net> To: Nathan Stratton <nathan@robotics.net>; Sean Donelan <sean@donelan.com> Cc: <nanog@merit.edu>; Dzh-Marc <dzh-marc@fw.networktwo.net> Sent: Tuesday, October 10, 2000 4:00 PM Subject: RE: Power monitoring Re: Power Outage in Chicago Loop
I'll bite ...
I've been looking for a unit that monitors just those parameters (voltage and current on each phase as well as DC voltage, DC Current, temp, and humidity) for the same reasons. Would you care to share how it's being done?
Dave

After my first summer in PG&E country, I've been wondering if there was a way for ISPs to share power quality data about the local utility. For the most part, every ISP in a region experiences the same woes and problems of the electric utility. Most ISPs are capable of at least minimal monitoring. If the shared data was limited to only the upstream side of the ISPs power system, it would show the performance of the utility; but ISPs could still keep any internal problems secret. While a power quality meter would be nice, even SNMP capable UPSes can report basic data.
We are just now starting to graph voltage and current on each phase as well as DC voltage, DC Current, temp, and humidity. We are doing all this via AI Spy units in each pop.

What is "normal" power throughout the country? How severe can power get?
Well that thing that freaks me out is the voltage swing over a given day. At first I thought the problem was that the building did not have large enough feed, but now that we are graphing voltage on other datacenters we see the same trend. We see voltage swings in my cities of up to 25 volts every day.
