The check_ups plugin was created to facilitate monitoring of a number of UPS vendor products.  To use the plugin you will need to install UPSD daemon distributed with Russel Kroll’s Smart UPS Tools on the remote host.  (See the REQUIREMENTS at the end of this post).

I do however believe that this plugin works with the old NUT API, which has been deprecated when switching from 1.4 to 2.0 version of NUT.

Notes:
This plugin attempts to determine the status of a UPS (Uninterruptible Power
Supply) on a local or remote host. If the UPS is online or calibrating, the
plugin will return an OK state. If the battery is on it will return a WARNING
state.If the UPS is off or has a low battery the plugin will return a CRITICAL
state.

You may also specify a variable to check [such as temperature, utility voltage, battery load, etc.]  as well as warning and critical thresholds for the value of that variable.  If the remote host has multiple UPS that are being monitored you will have to use the [ups] option to specify which UPS to check.

REQUIREMENTS
This plugin requires that the UPSD daemon distributed with Russel Kroll’s
Smart UPS Tools be installed on the remote host.  If you do not have the
package installed on your system, you can download it from http://www.networkupstools.org
