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

 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.

 This plugin requires that the UPSD daemon distributed with Russell Kroll's
 Network UPS Tools be installed on the remote host. If you do not have the
 package installed on your system, you can download it from
