1. Monitor Power Usage With Your UPS

    Wed 18 November 2009

    If a system is connected to a UPS (Uninterruptible Power Supply), it is possible to determine how much power it consumes. For this purpose, I wrote a small script:

     Host:~# ./ups.sh
    
     UPS model: Back-UPS RS 1200 LCD
     APC model: Back-UPS RS 1200 LC
     Capacity: 720 Watt
     Load: 18 Percent
     Usage: 129 Watt
     Time left: 33 Minutes
     Status: ONLINE
    
     Host:~# ./ups.sh
    
     UPS model: Back-UPS RS 1200 LCD
     APC model: Back-UPS RS 1200 LC
     Capacity: 720 Watt
     Load: 19 Percent
     Usage: 136 Watt
     Time left: 22 Minutes
     Status: ONBATT
    

    This script assumes that:

    1. You are running a unix

    2. You run apcupsd

    The script can be downloaded here:
