apcupsd also supports SNMP, and the usage of the network monitoring
cards. I find that works better for my usage, because a given host on
my Smart-UPS 5000 might be down at any given moment for testing, and if
its the one with the single usb connection, I'm out of luck. Instead, I
have apcupsd on each host talking to the UPS's onboard NIC and running
independently, with the ability to power off the UPS disabled (by using
the read-only SNMP community).
