UPS SNMP works on TrueNAS Core but not on Scale with same settings

Description

UPS: Eaton 9PX with NMC card

SNMP v1 and v3 are turned on and v1 has public account (read only) activated.

v3 has readuser activated and password protected.

The Core TrueNAS-13.0-RELEASE is installed on a TrueNAS Mini XL+

The Scale TrueNAS-SCALE-22.02.1 is instaled on a Lenovo SR655 server

Both uses Mellnox SFP28 25G NIC and connect to a switch.

ping UPS ip address works on both Core and Scale from Shell.

TrueNAS Scale/Debain: /etc/nut

TrueNAS Core: /etc/local/nut

I have checked all conf files in /nut folder on both Core and Scale.

They are exactally the same.

The Core

upsc UPS2_Eaton9PX

returns the UPS status info.

But the Scale returns Connection refused.

ups.conf

[UPS2_Eaton9PX]
driver = snmp-ups
port = 192.168.101.22:161

upsd.user

[readuser]
password = xxxx
upsmon master
public

User found the solution to the configuration issue and when they upgraded the other issue was resolved.

Hi Bonnie,

I would love to help with the ixsystem development and bug fix.

However, on our main server, due to some policy, I cannot provide the debug log at this time. 

I am happy to report that on our non-production server, a freshly installed TrueNas Scale 22.02.2 doesn't have the same issue (the issue happened on 22.02.1).

I guess that the latest version (released a couple weeks ago) already fixed the issue. 

 

You may close this ticket now.

Thank you very much.

Thank you for the report, .

Can you please attach a debug file to the "Private Attachments" section of this ticket?

To generate a debug file on TrueNAS SCALE, log in to the TrueNAS web interface, go to System Settings > Advanced, then click Save Debug and wait for the file to download to your local system.

Fixed this issue when I found this post.

Thanks!

upsc UPSNAME command can now returns ups status. 

 

But the Reporting - UPS graph doesn't seems to work.
