UPS monitoring with NUT

Ok, monkey see monkey do so I’ve followed instructions but getting nothing coming up with UPS NUT

https://www.luzem.com/2015/01/25/install-ups-in-centos-7/
and

librenms/librenms-agent/blob/master/snmp/ups-nut.sh

# Instructions:                                                #
# 1. copy this script to /etc/snmp/ and make it executable:    #
#    chmod +x ups-nut.sh                                       #
# 2. make sure UPS_NAME below matches the name of your UPS     #
# 3. edit your snmpd.conf to include this line:                #
#    extend ups-nut /etc/snmp/ups-nut.sh                       #
# 4. restart snmpd on the host                                 #
# 5. activate the app for the desired host in LibreNMS         #

Just a question …I never understand UPS NUT… why not just add the UPS into librenms we already pull of that data and more.
lIbrenms pulls all the data UPS Nut does. so why use NUT?
just curious

scracha · 10 October 2017 02:09

Update. In librenms I removed the UPs nut app. Then reselected it.

scracha · 10 October 2017 02:10

Most consumer grade UPS’ only have USB or serial interfaces with no SNMP support. I’ve got little micro-pops that justify a cheap $100 UPS not a $500 one with network support.

Kevin_Krumm · 10 October 2017 02:33

makes sense thanks for the reply

scracha · 10 October 2017 02:54

I’d appreciate any help on how to set up an alert for application UPS-nut for when say, voltage input dropping below 220V?

Kevin_Krumm · 10 October 2017 03:04

check the database look the table for applications… you can alert in the that. run this query.

select * from applications;

I don’t use UPS NUT so im not sure exactly how the table looks like but your alert rule may look something like this,

%applications.app_type = "ups-nut" && %applications.app_status < "220" &&

scracha · 10 October 2017 20:27

Hmm. Thanks for the help Kevin. Nothing in app_status seems to be stored in the DB.

mysql -u librenms -p
use librenms
select * from applications;

Kevin_Krumm · 10 October 2017 21:16

Im not sure where that data is stored in the DB then.

Does anyone has a guideline to connect NUT and upsd to an APC SNMP Network Mgmt Card 2 (AP9630) via SNMP instead of connecting locally via USB?

Thanks in advance!
