Power Analysis/Management Tools

[Brandon Galbraith <brandon.galbraith () gmail com>]

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.
