I can only find SNMP_INFO when I discover on this device - EATON UPS with WEBCARDLXE nmc.

Tried using v1 and v2c and nothing else gets discovered.

basic snmpwalk seems fine.

I tried manually running –checks=ups_in_voltage -vvI from cli but the service goes to “vanished” 

this is a new device we’re trying to monitor, any suggestions?

First step would be to create an SNMPwalk and take a look at the first lines of this walk.

Important are the first two line.

.1.3.6.1.2.1.1.1.0 Linux NAS 4.4.302+
.1.3.6.1.2.1.1.2.0 .1.3.6.1.4.1.8072.3.2.10

Here you will see some text and normally an enterprise OID. If you can post these it is possible to look why nothing is discovered on your device.

.1.3.6.1.2.1.1.1.0 = STRING: Ubuntu 18.04 Linux 4.4.31 flash: 3.38G ram: 506844kB processor: armv7l software: PowerAlert 20.2.1 (Build 942)
.1.3.6.1.2.1.1.2.0 = OID: .1.3.6.1.4.1.850.1.1.1

It is not a real Eaton UPS but a Tripp Lite. Eaton bought them in 2021.

But in general Tripp Lite UPS should show more than SNMP info check. I see why your system does not show anything. The support for Tripp Lite OIDs was added in version 2.3.0p11.
If you upgrade your CheckMK to a more current version it should show something.

thanks that makes sense -

question then – since my current deployment (primary and all distributed nodes) are running older version due to OS limitation, is it safe to run a separate distributed node running

still no improvement, despite new instance being on latest 2.4. version…

only services discovered are SNMP Info and Uptime … =(
