Configure UPS monitor using NUT on Debian
Quick steps to configure UPS on Debian 8 (jessie).
Connect UPS to Server
1. Recommended shutdown server and disable power before connect if it’s RS-232(COM
port);
2. Check correct device path from “dmesg” output;
Install
1. Required to install nut-client, nut-server
2. For collecting data into RRD database we also need to install Collectd with NUT plugin;
sudo -i
aptitude update; aptitude install nut-client nut-server collectd
dpkg -l | egrep "nut-|collectd" | awk '{ if ($1=="ii"); print $3"\t"$2}'
5.4.1-6+deb8u1 collectd
5.4.1-6+deb8u1 collectd-core
5.4.1-6+deb8u1 collectd-utils
5.4.1-6+deb8u1 libcollectdclient1
2.7.2-4 nut-client
2.7.2-4 nut-server
Configure
Configure NUT server - first. If it will not work anything else - is not important :) Check your serial
port path and replace /dev/ttyS0 if it’s different.
No meu caso foi dev/ttyACM0
cat >> /etc/nut/ups.conf << EOF
[ups]
driver = solis
port = /dev/ttyACM0
desc = "UPS"
EOF
If you are using USB connection than change “driver” variable also with path.

Testing
Testing NUT-server by starting plugin binary manually:
root@server:~# /lib/nut/solis -a ups
Network UPS Tools - Megatec/Q1 protocol serial driver 1.56 (2.7.2)
Duplicate driver instance detected! Terminating other driver!
Supported UPS detected with megatec protocol
Vendor information unavailable
No values provided for battery high/low voltages in ups.conf
Using 'guestimation' (low: 10.400000, high: 13.000000)!
Battery runtime will not be calculated (runtimecal not set)
Data returned OK. If you see error with connection - check file /dev/ttyS0 permissions.
ls -lah /dev/ttyS0
crw-rw---- 1 root nut 4, 64 Nov 16 14:43 /dev/ttyS0
If after all you still see error - try different port.
Configure UPSD with minimal options:
echo "LISTEN 127.0.0.1 3493" >> /etc/nut/upsd.conf
service ups-monitor restart
Check UPSD is listening local interface only and is up:
$ netstat -tnlp | grep ups
tcp 0 0 127.0.0.1:3493 0.0.0.0:* LISTEN
4585/upsd
Configure NUT client:
echo "MODE=standalone" >> /etc/nut/nut.conf
Testing
Testing NUT-client connection to NUT-server
root@server:~# upsc ups

Configure RRD database
Let’s configure NUT plugin for collectd
cat >> /etc/collectd/collectd.conf.d/nut.conf << EOF
LoadPlugin nut
<Plugin nut>
UPS "ups@localhost:3493"
</Plugin>
service collectd restart
Check new files created with RRD database data:
root@server:~# ls -1 /var/lib/collectd/rrd/server/nut-ups/
frequency-input.rrd
percent-charge.rrd
percent-load.rrd
temperature-ups.rrd
voltage-battery.rrd
voltage-input.rrd
voltage-output.rrd
Options about UPS actions can be checked here:
egrep -v "^#|^$" /etc/nut/upsmon.conf
MINSUPPLIES 1
SHUTDOWNCMD "/sbin/shutdown -h +0"
POLLFREQ 5
POLLFREQALERT 5
HOSTSYNC 15
DEADTIME 15
POWERDOWNFLAG /etc/killpower
RBWARNTIME 43200

Now we can open this database using GUI or via web-collectd Frontend:
