UPS Support

I have written some code to monitor my UPS connected to my server. You have to install upsd/nut and setup ACL. Define a UPS device with address field filled with the name of your ups as you defined it in the config files. Check parameters and enable module in the Setup UPS Monitor menu.

Only 3 parameters are monitored, ups temperature, input voltage and ups status.

OL	Online
OB	On Battery
LB	Low Battery

I have tested it with my APC SmartUPS 1000.

Install Pre-Requisites

sudo apt-get install upsd nut

Here some of my config file snippets.

cat /etc/nut/ups.conf
[smartups1000]
        driver = apcsmart
        port = /dev/ttyUSB6

cat /etc/nut/upsd.conf
ACL mynet 192.168.100.0/255.255.255.0
ACL localhost 127.0.0.1/32

ACCEPT mynet
ACCEPT localhost

cat /etc/nut/upsmon.conf
POWERDOWNFLAG /etc/killpower
MONITOR smartups1000@localhost 1 monmaster MASTERPASS master
SHUTDOWNCMD "/sbin/shutdown -h now"

cat /etc/nut/hosts.conf
MONITOR smartups1000@localhost "Cyberjunky's UPS"

cat /etc/nut/upsd.users

        password = ADMINPASS
        allowfrom = localhost
        actions = SET
        instcmds = ALL

[monmaster]
        password = MASTERPASS
        allowfrom = localhost
        upsmon master

[monuser]
        password = USERPASS
        allowfrom = localhost
        upsmon slave
