We have 4 Eaton UPS and none of them report incorrect voltages for Input, Output, Bypass and Battery.
Eaton is compatible with RFC 1628 for the models we have (9130 UPS and PW9130 3000VA-R) and LibreNMS collects voltage data from this MIB OIDs.
What model do you have? What values do you see via SNMP?
Both of them have the same network card (NetworkMS). The EX is a bit old and has an older hardware revision of the network card and therefore not the latest software revision, “just” HF instead of KB for the newer.
About SNMP values, good question which OID to look at?
From the management web interface I see the correct values (e.g. 237 Volts) in LibreNMS I see 23.7 Volts
Did you add these devices recently and have the issue right away, or did they change their behaviour recently ?
I did push a change for eaton-mgeups device (they were not at all discovered) and had this kind of divisor issue.
If there is no uniform reply of the eaton devices, we’ll end up with some kind of table to map devices and divisors and that would be a pain to maintain …
PipoCanaja, I have 6 eaton ups that all broke on the Wednesday night upgrade this week. Input/Output/Bypass are all reporting around 12v and should be around 120 just like nova-2nd posted. They have been working fine for years. So something defiantly broke on that update. If you need any info from me, let me know what you need and I hopefully can help. Thanks, Craig.
