I'd think SNMP will be what any product uses to query APC gear, even their own suite uses SNMP to collect information and receive traps. We use cacti to graph our loads on the APC power bars and UPS gear, gives you everything you need on all phases/legs, was there something in particular you were after? -g -----Original Message----- From: Brandon Galbraith [mailto:brandon.galbraith@gmail.com] Sent: Monday, October 26, 2009 4:59 PM To: nanog@nanog.org Subject: Power Analysis/Management Tools Not to go too off-topic, but if there is a more preferred location for me to ask, please let me know. I'm looking for recommendations on open source packages that people are using for monitoring power utilization of their network/server gear. We're using Cacti currently, pulling the data from APCs via SNMP, and I wanted to check if someone had come across a better method before I reinvented the wheel.
