NUTUPSMonitor

1. Install network ups tool;

# yum install nut nut-client

2. Change mode from none -> standalone in /etc/ups/nut.conf

#MODE = none
MODE = standalone

3. Add a UPS device in /etc/ups/ups.conf;

• Use auto for port if USB

[drewups]
        driver=usbhid-ups
        port = auto
        desc = "Office UPS"

4. Create a master to use to communicate with nut in /etc/ups/upsd.users;

[amasteruser]
       password = anawesomepassword
       upsmon master

5. Create a user on the system to monitor;

 # useradd -s /sbin/nologin -g nut nutmon

Configure /etc/ups/upsmon.conf to monitor drewups as amasteruser, run a script when an action occurs, as well as alert;

RUN_AS_USER nutmon

MONITOR drewups@localhost 1 amasteruser anawesomepassword master
