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:
-
You are running a unix
-
You run apcupsd
