Hi Alex, We monitor almost 400 20amp and 30amp 110V and 208V circuit breakers in our data center in San Deigo. We utilize a system called Data Trax which is tied into our Remote Power Panels and monitoring gear made by a company called Invensys. Our power comes from our UPSs, ties into redundant PDUs and then hits the RPPs where we pick up load with inductive donuts. In our case, the Data Trax system alerts us is the usage goes over a certain amperage that we set. As we sell 1/3 cabinets and only allow customers 5.33 amps, we set those to alert (via e-mail, trap and visual warning in my NOC) when those customers go over 5 amps. On standard 20 amp circuits, we alert at 15 amps. The customer is also notified at the same time via e-mail so they can take corrective action. We utilize the same system to monitor our DC plants as well. The system works very well for us. Hope this helps a bit. Let me know if I can answer any other questions. http://www.invensys.com/ On Thu, 15 Jan 2004 01:33:52 -0500 (Eastern Standard Time) Alex Rubenstein <alex@nac.net> wrote:
Preamble: We run a colocation center. We sell power to customers.
Question: We are looking for something that sits in the PDUs or branch circuit-breaker distribution load centers, that, on a branch-circuit by branch-circuit basis, can monitor amperage, and be queried by SNMP.
Considering there are several hundreds of circuits to be monitored, cheap and featureless (all we need is amperage via SNMP) is fine.
Looked at things like Square-D PowerLogin stuff, but thats very pricey, and does about 30x what we need.
Pointers? URLs? Experiences?
Thanks.
