Cacti is a cracking bit of software, but I found this difficult to integrate and customize to what we required. I ended up writing our own, custom pollers, Database backend, web frontend and rrd to generate the graphing. We were quoted something like £50k for something awfully similar..

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.
