Dockable UPS Monitor

## NAME

WMNUT - Dockable UPS Monitor

## SYNOPSIS

**wmnut** \[-A T1 T2\] \[-b BlinkRate\] \[-B BeepVolume\] \[-C CriticalLevel\] \[-d display\] \[-h\] \[-l\] \[-L LowLevel\] \[-U upsname\] \[-v\] \[-V\] \[-w\]

## DESCRIPTION

WMNUT is an UPS Monitor. It is used to visually display and interpret details of up to 9 UPSs status via NUT - Network UPS Tools framework.

WMNUT is dockable using WindowMaker and AfterStep window-managers; under other window-managers, WMNUT should be used with "-w" option to appear as a nicely-sized 64x64 application with a background.

WMNUT provides the following information:

- \- Status of power supply (Blinking Red/Yellow/Green colored meter/battery),

  - \- Percentage of battery remaining (numeric and meter),

  - \- Load level percentage on output (numeric, if available),

  - \- Runtime to empty, ie time left to battery depletion (MM:SS),

  - \- Communication status with UPS (Blinking Red/Green "C").
