+'''upsd''' is the server, '''upsmon''' is the client.
+
+* __ups.conf__ - this defines the UPSes that are connected to the server. You might see a process running like "''/lib/nut/newhidups -a YOUR_UPS_NAME''"
+* __upsd.conf__ - the ''upsd'' daemon is the interface for other programs to connect and query the directly-connected UPSes. This config file controls some access restrictions.
+* __upsmon.conf__ - ''upsmon'' is the program that periodically connects to upsd to get the status, and can run commands (eg to shutdown your server if the battery gets low)
+
+Other things like [Nagios] have their own clients that connect directly to ''upsd'' to query the status.

!! Sample Configuration
This is a simple way of setting up the NUT ups monitoring system to shut servers down well before you get to powerfail status. If you lose power for more than about 5 seconds, chances are pretty good you're going to have lost it for a while, so you may as well shut things down now
